Frontend driver patch

Hi,

Attached is a path that provides a way to get at the path of libcompiler_rt
from the frontend much the same way '-print-libgcc-file-name' works to get at
libgcc.a

We need this (it blocks us) in Coreboot.org as our build system is very low
level and this kind of granularity of control is used during link-time with our
rather demanding/tentative linker scripts.

Seems people in the IRC are very busy these days to quickly take care of this
one so i'll leave it here. I've done my best on the test case also so this is
like 98% the way there, I just need someone to take care of the rest.

Kind Regards,
Edward.
