Let's check for e.g. --help anywhere in the ARGV array rather than just
the first value to avoid brew upgrade --help causing problems.

There are other hard-coded uses of HEAD, in build_options for instance.
These all need to be fixed before enabling this.
Homebrew currently recognizes "--head" during the install process, but
rather than actually fetch HEAD it just nags the user to use the
correct option. Since we recognize the spelling anyway, this just
promotes the lowercase version to an official alias.
ClosesHomebrew/homebrew#26555.
This raise happened in no other ENV methods, and isn't really necessary
since fails_with guards against this method actually being called unless
gcc-4.2 is actually installed.
Since ENV.cc/cxx are accessors to ENV, any values being passed through
are coerced into strings, which means that a nil `ENV.cc` is actually
an empty string - which isn't considered to be false in Ruby.

The traditional approach to installing the dependencies of a formula is
the following:
brew install `brew deps formula`
This approach ignores any options that are specified in the parent
formula. This pull request adds a --only-dependencies option to brew
install that installs the dependencies of a formula with optional flags,
but returns before installing the parent formula.

The mapping of architectures to optimization flags is now retrieved from
Hardware::CPU and the selected flags are passed as an environmen
variable, rather than duplicated in the cc wrapper and re-calculated on
every invocation of the compiler.
ClosesHomebrew/homebrew#24540.
Constructing the path relative to a file in the repository is incorrect
on some supported configurations (i.e., the repository is located in a
different place than the prefix).
ClosesHomebrew/homebrew#24418.
The cc wrapper's make_fuss is only enabled when HOMEBREW_CCCFG contains
'O', which is set by the make wrapper. This means it is disable when
running configure scripts. However, this does not include configure
scripts invoked by make, which inherit the value of HOMEBREW_CCCFG from
the make process. make_fuss will be enabled for these scripts, cause
breakage.
Configure scripts generated by autoconf 2.56 (November 2002) or later
export DUALCASE into the environment of subprocesses. This variable is
only used by the MKS shell, so we can use it as a heuristic to determine
if we are running as a subprocess of a configure script.
