Heh, great minds think alike ;)

Something else more-or-less related that I think we should
fix/workaround until the relocatable sdk rpath handling gets integrated
is the issue about the toolchain linking to gmp/mpc/mpfr, and not
finding our libraries when the toolchain is moved.

That is currently quite painful, especially when you want to reuse the
toolchain on different machines/distributions, that may not have
compatible libraries in /usr/lib.

The easiest workaround is just to build our host-gmp/mpc/mpfr statically
for now. This has minimal size impact on the toolchain (< 1MB for a
.tar.gz of output/host).
