Bug 1112974 - Try to find llvm-config through clang first before looking at $PATH; r=glandium

Browse Source 
Right now, if the LLVMCONFIG variable is not set in the .mozconfig, we
first look for the system default llvm-config and only then we ask clang
itself, which breaks building with the clang plugin if you make $CC and
$CXX point to a non-default clang binary.  This patch fixes the issue
by reversing the search order.
