This is a workaround for the infinite loop reported at
http://keeda.stanford.edu/pipermail/klee-dev/2011-August/000723.html

KLEE needs to use --fno-builtin when compiling its version of memset.
However, this patch also adds the workaround suggested by Paul in the
thread above, since support for --fno-builtin was added to llvm-gcc only
after LLVM 2.9 was released.

Thanks to Paul and arrowdodger for their explanations and patches.
