  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.
