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

MPC8572). It uses eglibc (for e500/SPE patches) and a recent gcc (4.6.0,
yann@2173

for e500v2 DPFP support) and will generate appropriate dual-precision

Note: If building a Linux kernel with this toolchain, you will want to make

     9
sure -mno-spe AND -mspe=no are passed to gcc to prevent SPE ABI/instructions

    10
from getting into the kernel (which is currently unsupported). At this time,
yann@2173
    11
the kernel build system properly passes those two options, but older kernels
yann@2173
    12
were only passing -mno-spe by default."
