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`.

Even though we now prevent linking of this file into the prefix in
Keg#link, its presence still triggers a "non-lib in lib" warning during
installation. So keep cleaning it, and leave the check in Keg#link so
things that skip_clean 'lib' still won't have it linked.

This still isn't perfect, but it will handle hyphens in formula-names better now. A proper solution is not easy or maybe even possible unless we ban hyphens in versions AND formula names, or use a different character as a separate in downloaded cache files which we then ban from formula-name and version strings.

It is fucking amazing how much shit breaks if CWD is invalid. Fucking amazing.
Also fuck you dumb user who can't figure out what "No such file or directory - getcwd" means so you force me to waste half an hour fixing it for you.
A common source of compile error, lets tell the user straight away.
Removed relevant documentation from the installation instructions as a consequence.
Because we should do as little modification to the system as possible.
Even though /usr/local doesn't exist on a virgin OS X, many tools create it, and some of them expect /usr/local to be root owned for security reasons.
This modification fixes Airfoil on systems where it is installed.
The result of this is we can no longer create new directories in the HOMEBREW_PREFIX unless we check and prompt for sudo first when required.
