Note that just moving ports debug data to /usr/local/lib/debug/...
won't work since GDB won't search there.  We could teach it to search
a list of paths and include /usr/local/lib/debug and /usr/lib/debug,
or perhaps a symlink under /usr/local/lib.

We could also use a .debug subdirectory for ports and other users of
bsd.lib.mk - so for example /usr/local/lib/libfoo.so would have debug
info in /usr/local/lib/.debug/libfoo.so.debug.
