complibs: better deduce whether to backup complibs or not

To decide whether we need to backup the companion libraries,
do not rely on the !shared case. In the future other cases
may require not to save the companion libraries (eg. if using
the ones provided by the host distro).

The gcc-3.x toolchains would contain all the targets by default.  With gcc-4,
yann@552
     3
you have to actually list out the multilibs you want or you will end up with
yann@552
     4
just one when using targets like 'sh4-linux-gnu'.

The resulting toolchain can't even build a kernel as the kernel needs to build
yann@552
     7
with the nofpu flag to be sure that no fpu ops are generated.

Here we restore the gcc-3.x behavior; the additional overhead of building all
yann@552
    10
of these multilibs by default is negligible.
