Which sounds just right to me.  I don't see how putting shared
libraries in $(libdir) can possibly work in the presence of
multilibs.  Perhaps we should have a hook that creates a soft-link
only for the main copy of the library?  I really think that having
libgcc_s.so and any other libraries directly in $(libdir) is wrong,
precisely because of the multilib issue.  We've always deferred the
tricks to get programs to find libraries at run-time to program
builders, so my change doesn't change the status quo.  In fact, having
libg2c.so.0 installed in $(libdir) would only help avoid this if you
set prefix to /usr or /usr/local, whose lib subdirs are typically
searched by default, or add $(libdir) to /etc/ld.so.conf, in which
case you might add the correct, multilib-aware location as well.
