Fix llvm loading when calling through a symlink.

	mini-llvm.h: When trying to load mono from ./.libs or ../lib we did not
	resolve the current binary for symlinks. This failed on OSX since
	everyone calls /usr/bin/mono while libmono-llvm was on
	/Library/Frameworks/Mono.framework/Versions/Current/lib.

	This make mono --llvm work on release mono.
