The experiment to add `-no_weak_imports` unconditionally has been a bit
of a failure. It's broken more than it's fixed and I don't think we can
have this as a default for Xcode 8.
Add `ENV.no_weak_imports` to be used by formulae authors and make
`ENV.no_weak_imports a no-op (for now).
We may reconsider this behaviour in future.
Issue Homebrew/homebrew-core#3727 suggested we set -no_weak_imports for
new versions of Xcode to ensure that e.g. building on 10.11 against the
10.12 SDK doesn't result in a situation where autotools thinks symbols
exist that don't actually exist on the current platform.
Further discussion in golang/go#16770 revealed that some packages
require weak imports to build normally.
In fact, we don't really care about undeclared dependencies for optional
installations. Because, this is mainly used to help us to detect breakage
for bottles so we can do a revision bump.
Switch to HOMEBREW_LIBRARY since HOMEBREW_LIBRARY_PATH already includes
"/Homebrew" and HOMEBREW_LIBRARY is less confusing.
Closes#530.

Substitue each Version.new and HeadVersion.new with Version.create
to unify Version and HeadVersion instantiation among core code.
Note that this does not relate to Mac::OS::Version class.
Move some stuff formerly in `Library/ENV` around:
- Move `Library/ENV/$XCODE_VERSION` to `Library/Homebrew/env/super` as they are
all superenv wrappers and all symlinks to the same version. We never needed
the "separate shims for separate versions" functionality and it just adds
confusion.
- Move `Library/ENV/pkgconfig` to `Library/Homebrew/env/pkgconfig` to get more
things under `Library/Homebrew`
- Move `Library/ENV/scm` to `Library/scm` as these wrappers are not actually
used by or related to superenv (or stdenv) in any way.
In 0d189fae57
we completely removed `effective_sysroot`, which consequently left all the
`effective_sysroot`/usr/include calls pointing at `/usr/include`. This is wildly
problematic on systems where the Command Line Tools aren't installed because
`/usr/include` is not a default-created folder prior to CLT installation.
I'm unsure if `effective_sysroot` should still be mentioned in Library/Homebrew/extend/ENV/super.rb
at all. If it can be deleted, feel free to do that without waiting for me to review.
This seems to fix:

Beta versions of XQuartz have address sanitization enabled, which
breaks some software at runtime, including wine.
