What's the right way to do host libraries required for gcc

I can't think of a better way at the moment, but perhaps after the
toplevel is autoconfiscated you could add some code there to detect a
buildable or installed libbanshee, and pass a --with-banshee= flag to
gcc's configure accordingly.

A long-term idea would be to make configuring host subdirs part of the
toplevel makefile (much like target configs are), so we could have
configure-gcc depend on build-libbanshee.  Then it would even handle
banshee build errors gracefully ;-)
