Ed Maste bff207520a libgcc_s: add libm dependencies from div{d,s,x}c3
compiler-rt's complex division support routines contain calls to
compiler builtins such as `__builtin_scalbnl`.  Unfortunately Clang
turns these back into a call to `scalbnl`.

For now link libm's C version of the required support routines.
