X86 Linux compiles/links/runs just fine.
X86JITInfo is an object file that should be part of LLVMX86.o. To
validate that it is there do this:
cd <builddir>/lib/Target/X86/Debug
ls -l X86JITInfo.*
The two files (*.o and *.d) should have non zero size. Then do this:
nm X86JITInfo.o
and make a note of a few external symbols (with T attribute). Then
run nm on LLVMX86.o in the <builddir>/Debug/lib directory and see if you
can see that symbol (might want to pipe through grep for that). If the
symbol shows up then X86JITInfo.o was linked into LLVMX86.o
The LLVM Makefile system is pretty simple (to use). Its fully documented
here: http://llvm.cs.uiuc.edu/docs/MakefileGuide.html
