Suggestions:

1. Follow Solaris.  Put the dl* stubs in a "libdl" used only by libc.so
   (libdl would not be used by the static libc.a).

2. Make a libc.so with dl* stubs, but ensure that they are not in libc.a.

In both cases, the locale(3) implementation must have a version in libc.a
that does not require dlopen()... probably a stub.
