 I understood why the shared lib. was being deleted from reading
 the Makefiles, but, they should remove the file _only when_
 DELETE_INSTALLED_LIBGCC=yes, right? As the test currently stands,
 libgcc_s.so* is deleted unconditionally, which results in link
 failures for users who don't install the `comp' set, preferring to
 get their compiler from pkgsrc.
