ISSUE: ExternalFunctions.cpp::lookupFunction() calls dlsym(RTLD_DEFAULT, ...). In glibc, dlfcn.h does not make RTLD_DEFAULT visible unless _GNU_SOURCE is #defined. Unlike the evil money-grubbing non-free software pigs at sun, the FSF is trying not to pollute the C namespace. 
ACTION: Hack the Makefile to #define _GNU_SOURCE while compiling in tools/lli. Yes, I know that this is ugly.
PATCH: Apply from llvm top-level directory with "patch -p0".

Applied. I actually applied this to the top level Makefile.common file so
that all directories get it:
