[LLVMdev] Linux-x86 Compatability

[Casey Carter]

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".
