Yup.  It's going to be painful, but yes, that's where we're heading long
term.  The first (of several) steps is to get libgcc out of the GCC
directory and into a target library directory in a manner similar to
libstdc++, libobjc, etc.  Once we've untangled libgcc from living in the
gcc subdir we can look into getting its install location moved, API versioning
the library then making it a shared library.

This is going to be a nontrivial amount of work.  But ultimately it's
necessary to deal with a variety of losing behaviors we've got right now
in the compiler.  There's basically no way to win with libgcc as an archive
library.
