[Mesa-dev] [PATCH] Use AC_PATH_TOOL instead of AC_PATH_PROG for llvm-config.

[Michał Górny]

This should help with cross-compiling and multilib when $CHOST-specific
llvm-config is expected rather than build host default one.

It will help us a bit in Gentoo where we've started using
i686-pc-linux-gnu-llvm-config for 32-bit multilib LLVM.
