The 'llvm' way is supposed to be disabled in the testsuite if LLVM is 
not found.  Here is the code from testsuite/mk/test.mk:

ifneq "$(shell $(SHELL) -c 'llc --version | grep version' 2> /dev/null)" ""
RUNTEST_OPTS += -e ghc_with_llvm=1
else
RUNTEST_OPTS += -e ghc_with_llvm=0
endif

Maybe this isn't working?  Or maybe you have llc on your path, but 
there's something wrong with it? Which test is failing specifically?

Cheers,
