I would expect that it would go in the same place as libbfd.so and
libstdc++.so, or any other library we built, which depends of course
on whether or not we are cross-compiling or cross-hosting.  That is, I
would expect to see it in /prefix/lib for a native build.

The interaction with multilibs may be more interesting.  Perhaps we
will want to build libgcc-nof.so?
