this is because the supporting libraries like mpc mpfr that are needed
by gcc itself to run
we might have different versions of these libraries. So depending upon
shared objects
would mean we need to find same shared objects where say the SDK is installed
so either we ship the whole baggage or we link it in statically. This
patch makes those libs to
linked in statically and cross gcc wont have dependencies on these
libs anymore so
it can run on all hosts pretty much.

Another different way to do it would be to build these libraries as
part of gcc-cross build in unified tree
and then gcc would automatically link in the static versions of these
libraries. As a downside
if the native versions of these libraries are needed elesewhere then
we will build that lib twice.
But it should be cleaner IMO to just build them intree with gcc.
