Yes, this is already my plan.  It is not going to happen too quickly,
but if someone works on it for a particular target - trivial or not -
it shouldn't be too hard to do.  You'd think the tricky part would be
handling shared libgcc, but actually I've already moved a sizeable
chunk of the shared libgcc code to the new directory.

Bootstrapping an entire GNU/Linux target system right now involves
several builds of GCC - as many as three.  I want to cut that down,
build the compiler first and at most a preliminary libgcc, and then
rebuild libgcc after glibc.
