Description:
When llvm is built, the file llvm-config.h produced harcode the host triple.

There is no problems when llvm is used to built binaries in a pure 64 bits or 32 bits environment,
but this design broke badly when building 32 bits binaries under 64 bits (here lib32-mesa).

See https://bugs.freedesktop.org/show_bug.cgi?id=44466
See https://bugs.archlinux.org/task/27645

The easier (and proper) is to use a similar workaround as provided by fedora:

Potential fixed PKGBUILD (only the llvm part is provided).
(application/x-gzip)    llvm-3.0-4.1.src.tar.gz (4.2 KiB)

Will config-32.h and llvm-config-32.h be provided by lib32-llvm?

Of course, and i already provide this in my mesa-git repo.

I just wait llvm to be "fixed" to upload the corresponding lib32-llvm.

llvm 3.1-1 in [testing] includes the fix.

Let me know if it works correctly.
