This should mean all those formula that pass options to aclocal don't need to anymore, but I'm not risking changing them.

We need these now for Xcode-4.3/CLT4X installations.

Also prevent m4 error in installer. And prevent brew doctor complaining if we're Xcode 4.3 or above.

Closes Homebrew/homebrew#10349. Fixes Homebrew/homebrew#10423. Refs Homebrew/homebrew#9179.

Apply the 'bin' audit to 'sbin' too, and also complain if subfolders are
installed to either.

Now individual formulae don't need to require this if they want to use
Hardware methods outside of `def install`.

There are still methods and variables with the word "folder" in the
name, but at least user-facing messages and warnings should use the
correct terminology.

This prevents passing nested arrays to exec; the same thing is done in
safe_system.

We set defaults for C and C++, might as well do the same for Objective-C and

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.

Calling Keg#unlink on "#{f.rack}/#{f.version}" will perform the unlink
relative to the _new_ keg, rather than the keg we are upgrading from.
Fix this by resolving the linked_keg entry and unlinking relative to it.

This file is installed by a number of packages, but it really shouldn't
be. It is meant to be updated by packages that use it, but this is
broken (1) by software that doesn't do this correctly and (2) by the
symlink being overwritten by Homebrew's linking code.

It's presence can cause issues with tools that use libiconv/gettext.

Instead let's follow MacPorts' example and just remove it during the
clean stage.
