complibs: split companion libraries to backend/frontend, a-la cc_core

Move the actual complibs codes to backend functions that builds the
required combo of build/host/target as requested by a frontend.

This split is currently a no-op, but is required for the upcoming
canadian-cross rework, where we'll be needing to build the complibs
twice, one for build/build, and one for build/host.

This applies to the six companion libraries:
- GMP
- MPFR
- PPL
- Cloog/PPL
- MPC
- libelf

     1 older verisons of glibc would build dl-sysdep as shared-only and dl-support as

     2 static-only.  alpha hooks in a cache variable via dl-auxv.h.  newer versions of

     3 glibc build dl-sysdep as both shared and static which means we now have symbol

     4 duplication for static builds with dl-sysdep and dl-support.  since dl-sysdep

     5 is both shared/static, there is no point in hooking dl-support anymore, so we

     6 can punt it.
