[BZ #157]cvs/fedora-glibc-20050211T0853
* include/libc-symbols.h (stub_warning): Emit a marker section called
.gnu.glibc-stub.NAME.
* Makerules ($(objpfx)stubs): Depend on object files, not dep files.
Use objdump to collect those marker section names.
($(common-objpfx)shlib.lds): Discard .gnu.glibc-stub.* sections.
