Trying to build a git checkout from today on Ubuntu Maverick with the --enable-gallium-llvm option the build fails with this:

It looks like it it's missing the -I from `llvm --cflags` in there:

-I/usr/lib/llvm-2.7/include  -DNDEBUG -D_GNU_SOURCE -D__STDC_LIMIT_MACROS -D__STDC_CONSTANT_MACROS -O2 -fomit-frame-pointer -fPIC

Without --enable-gallium-llvm that file builds fine.
