 Perhaps we should remove the static/shared libs options to the toolchain menu,
and make them depend on the libc choice rather than the other way round. That
way, we're sure that we never run into such impossible situations.

 Actually also some other options are more fitting in the toolchain menu IMHO,
like debug/optimization options and SSP.
