[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.
