Remove ports of obsolete and unmaintained upstream llvm/clang 3.2.

Mark pure as BROKEN by this removal.  It should be updated to a recent
release that supports llvm 3.5, but has seen no substantive updates in
over a year.

Cleanup plist

- Convert ports of devel/ to USES=python

Approved by:	portmgr (implicit)

In practice this port only builds on i386 and amd64 and that is not going
to change given that it is unmaintailed.

devel/llvm32: convert to new LIB_DEPENDS format

Approved by:	marino (mentor), portmgr (blanket)

Convert GMAKE to MAKE_CMD
Please note that lots of invocation of MAKE_CMD here are wrong as they do not
properly respect MAKE_ENV and friends

With hat:	portmgr

- Use python2 explicitly for the build

Reported by:	exp-run (PR 184591)
Approved by:	portmgr (blanket)

- Fix the usage of 'python' to get rid of the implicit lang/python
  dependency

Approved by:	portmgr (blanket)

Fix install with ASSERTS option enabled.

Submitted by:	Cary <cary@SDF.ORG>

Fix build with libc++ by importing r178240.

Submitted by:	tijl (via commit to devel/llvm)

Correct conflicting ldconfig config files by setting UNIQUENAME.

Strip installed libraries with ${STRIP_CMD}.

Some whitespace tidying.

Add missing distinfo file from r330777.

Add llvm32 and clang32 ports modeled on the llvm33 and clang33 ports.
These ports install binaries with "32" suffixes and most data lives in
${PREFIX}/llvm32 so there are no conflicts.

NOTE: devel/llvm and lang/clang will shortly be removed in favor of
these ports.
