SDK/usr/include and lib now appended instead of prepended.
Prepending overwrote our precedence of HOMEBREW_PREFIX/include and lib.

Undoing parts of the hot fix 78b9e8548e771a59e382e6f13339664ec5498391.
The only thing missing was to check for `system "/usr/bin/xcrun -find make 1>/dev/null 2>&1"`
and then it's safe to call locate.
This commit restores the original functionality but without the risk for recursion
and improves the logic of `MacOS.locate`. See below.
To important changes in this commit:
- For Xcode _and_ CLT: don't add the SDK and leave things as before.
So if `MacOS.clt_installed?`, then no `SDKROOT` and `-L` and `-I`
directories are set in `ENV.macosxsdk`.
- Improved the logic for `MacOS.locate` for Xcode-only situations
by assuring that the xcode-select path is correct. This is done
by checking that `bin/make` exists and is executable. Otherwise it
was possible to set xcode-select to an empty dir.
This check is done in `MacOS.sdk_path` too.
We are now able to use Xcode wherever it is and can work even, if
xcode-select is set to invalid values. (Remember some users don't
have sudo access and that is needed to fix xcode-select).
Some minor whitespace fixes.
Minor backtick fix in doctor.rb's printout.

Allow XCode without the Command Line Tools to
work with homebrew, so it's not necessary
to register an Apple Dev ID and/or go to the
XCode prefs and download the CLT. Yay!
Further, this commit allows to use the CLT
solely (without the need for XCode).
Saves quite some megs.
(Some furmulae require xcodebuild)
Of course XCode together with the CLT is still
fine and has been tested on 10.7 and 10.6
with Xcode 4 and Xcode 3.
Only on Lion or above, tell the user about the options,
which are
- Xcode without CLT
- CLT without Xcode
- both (ok, it's not directly stated, but implicit)
So if no Xcode is found and we are on Lion or above,
we don't fail but check for the CLTs now.
For older Macs, the old message that Xcode is needed
and the installer should be run is still displayed.
If the CLT are not found but Xcode is, then we
print out about the experimental status of this setup.

When referencing `Hardware.processor_count`, `ENV.make_jobs` will return an
integer. If referencing the environment variable `HOMEBREW_MAKE_JOBS`, it
returned a string.
Now, the function always returns an integer.

GFortran chokes when it is passed CPU flags specific to Clang. This change
ensures the environment variables `FCFLAGS` and `FFLAGS` contain the same CPU
flags that would be set for the GCC compiler.

All logic has been copied into a new method `set_cpu_flags` that accepts an
additional argument, `flags`, which contains a list of environment variables
for which the CPU flags are to be adjusted.
`set_cpu_cflags` now recalls `set_cpu_flags` and passes `cflags_flags` as the
first argument.

`ENV` methods that modify environment variables, `prepend`, `append` and
`remove`, can now accept lists of flags as well as a single flag.
The list of flags affected by `append_to_cflags` and `remove_from_cflags` are
now definied in a shortcut method `cc_flag_vars`.

The :force behavior for ENV.gcc has been the default for some time, and
was used to force vanilla gcc in case the gcc symlink pointed at
llvm-gcc; for ENV.clang, this doesn't mattera as clang is just clang.

The clang frontend ignores a number of options that are accepted by gcc
and llvm-gcc. However, it produces a warning for each unused argument at
each invocation, which can result in many lines of noise, e.g.
clang: warning: argument unused during compilation: '-rdynamic'
Since these arguments do not affect compilation, let's just silence the
warnings by passing '-Qunused-arguments' to clang by default.

Also xcrun can only exist at /usr/bin/xcrun.
Most of these edges are non-buildable environments, but I didn't know that when writing it, so it may as well stay, since it still does make brew --env more correct.
Using xcrun as a proxy to execute the compiler tools is per its design. This means you can't treat ENV['CC'] as a path anymore, but I think I found the cases this was being expected and corrected them. It was not proper anyway to assume the variable was a path, it can be anything. Like a proxy. Like xcrun.
Also more thoroughly clear ENV.
If we're going to unset GREP_OPTIONS we may as well unset this one too,
as it causes similar issues. Recent autoconf unset both of these.

This was probably a stupid decision in the first place. Who wants lengthy compile times for debatable gain? Apple use Os in all Xcode projects, so I'm guessing its the best choice.
Also I have long suspected the Image Magick performance issues Homebrew is supposedly susceptible to were because of O3.
Useful when CXXFLAGS has diverged fom CFLAGS, e.g. via ENV.append, and
also it is nice for CXX to have symmetry with CC.

Allow the use of a Homebrewed gcc-4.2 in order to support homebrew-alt's
apple-gcc42 formula.
This also removes the :force filtering for the gcc-4.2 check error.

In later XCodes, gcc is a symlink to gcc-4.2 which is itself a symlink
to llvm-gcc, so it is necessary to resolve multiple symlinks.

The compiler setting in the xcodeproj is overridden by the CC setting in the environment. This is a bit insane IMO since the xcodeproj itself has detailed decisions about what tools to use.
FixesHomebrew/homebrew#6406.
This is used with fails_with_llvm so that if GCC cannot be found (and we suspect this is the case with Xcode 4.2) the build will fail.
Quite possibly it should be the default.
