Hi Kev,

Non-Darwin Compiler-RT support for ARMv7 is patchy. I've ran some
tests and found some bugs (that I have yet to investigate and report),
but I wouldn't replace it yet in production, and certainly not when
cross-compiling, as I don't know if it even works.

It could be just a matter of fixing the CMake/autoconf files, or it
could be some more work, but if you're just trying to use LLVM instead
of GCC, I'd go without RT for the moment.

cheers,
