This allows overriding the "oldest CPU" behaviour - for instance, to
build Intel bottles for a newer CPU than Core 2, to build a PPC bottle
with or without Altivec on the same computer, etc.
This sets cpp to use the compiler as cpp, and works with scripts which
pass values to cpp on stdin as well as with file arguments.

This defines the new HOMEBREW_ARCHS environment variable, which is
currently only set during universal builds, so that the tool wrappers
no longer need to hardcode i386/x86_64.
If we're using a homebrewed gcc-4.2, xcrun may fail to find it (or,
worse, find superenv's shim instead). Explicitly add it to the PATH and
search all path elements for the requested tool.
Also make sure to specify 'gcc-4.2' as the compiler name, not plain
'gcc'. That can resolve to llvm-gcc and to gcc-4.0 on various Xcodes.
- The Library/ENV/4.3/xcrun shim now respects
ENV['DEVELOPER_DIR'] instead assuming the location
of /Applications/Xcode.app/Contents/Developer.
- The env var DEVELOPER_DIR is set if it is not
already. So, during superenv this var is always set
and we no longer have to care about people with unset
or wrongly set xcode-select stuff. This has been
a major PITA in the past.
- determine_developer_dir (which is used to set
the DEVELOPER_DIR var) now uses MacOS::Xcode.prefix
which is proven and very capable and uses splotlight
correctly.
- Replace (and remove) MacSystem.xcode43_developer_dir
with Xcode.prefix

Since 'gcc' is a symlink to 'llvm-gcc' on Xcode 4.3+, --use-gcc and
--use-llvm were doing exactly the same thing. Combined with the
previous commit, this allows users with either a leftover
/usr/bin/gcc-4.2 or a homebrewed apple-gcc42 to build with gcc.
This doesn't however fix Xcode-only systems with apple-gcc42.
FixesHomebrew/homebrew#17243.
xcrun has a lot of fallbacks if the first case fails but never actually
reaches them on CLT systems since it doesn't check the validity of the
first path before executing it.
(When should it reach these? Mainly for non-Xcode compilers we
support, e.g. apple-gcc42 which can be found by xcrun but which isn't
in /usr/bin)
The xcrun invocation also needed chomping.
Superenv normally filters out "-m32" flag, preventing 32bit builds.
Some software, however, still only work in 32bit mode.
If ENV.m32 is called, superenv does not filter out the "-m32" flag.
Also note, superenv, does not explicitly add the -m32 flag and
expects the build system of the software to know when and where to
provide this flag.

We already (correctly) allow -Wl, style linker arguments to pass
through; extend this to -Wp, (preprocessor) and -Wa, (assembler).

Superenv scripts have a stripped PATH, which may not include
the brew binary itself. Make this explicitly available to
superenv scripts.

stdenv already works as Contributions/cmds is in the path already.
This is safe to do because OS X already has git and svn in the PATH if you have the CLT installed. So we should definitely ensure we use the right versions.

Cleaned up the patch a little. Still ugly though, but logic is unusual so that's just how it is.
All logs are now stored from each command executed in Formula.install.
Error output is truncated to five lines in an attempt to not overwhelm the user and to encourage users to read the error output and report the bug properly. Maybe we can get that figure up from 70% to 90%.
Apparently setting RUBYLIB to '-' causes the library path to be unset. So we need to set our own library path in our scripts.
Fixes Homebrew/homebrew-versions/#47.
build-tool provided args must be considered first by cc, etc. Generally this already occurred for -I flags, because most of our -I flags were -isystem. However it didn't occur for keg-only flags and -L paths.
This was an error.
I amended the refurbishment code to ensure any paths we want to control the order of are thoroughly scrubbed out of the build-tool provided args. This ensures reliability for our builds.
However this path-scrubbing should always occur, even during configure (I am fairly sure of this). So more work is required.

We can't really execute c89/99 explicitly as these POSIX compliant tools support very few args. Best to execute clang or gcc with the --std=cx9 argument appended.
FixesHomebrew/homebrew#14724.
bsdmake used to be keg-only, so some users still have it unlinked (presumably they never run brew-doctor). Even though there is code to abort if dependencies are unlinked, it appears broken for this case. So let's just be thorough anyway.
