Fix superenv ENV[] hack

2013-08-19T17:32:58+00:00

We override ENV[] to always return strings under superenv, because
legacy formulae assume that CFLAGS, etc. are non-nil.

However, the current implementation has a bug. If I simply concatenate
ENV['CFLAGS'] with another string, it mutates ENV['CFLAGS']:

  irb> ENV['CFLAGS']
  => ""
  irb> ENV['CFLAGS'] + 'a'
  => "a"
  irb> ENV['CFLAGS']
  => "a"

Instead, let's simply return an empty string if the key doesn't exist.
This is sufficient because the following are equivalent:

  1. ENV['CFLAGS'] += "string"
  2. ENV['CFLAGS'] = ENV['CFLAGS'] + "string"

Re-enable superenv ENV[] hack

Reference self rather than ENV in Superenv module

2013-08-19T17:32:57+00:00

We want to be able to extend this module onto an arbitrary hash and use
it without mutating ENV, for testing purposes.

Move common stuff to extend/ENV.rb

Extend Superenv onto ENV instead of defining it on the singleton class

superenv: use Hardware::CPU.universal_archs

2013-08-16T05:46:57+00:00

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.
