x86: Use sysdep.o from libc.a in static libraries
Static libraries can use the sysdep.o copy in libc.a without a performance penalty. This results in a visible difference if libpthread.a is relinked into a single object file (which is needed to support libraries which check for the presence of certain symbols to enable threading support, which generally fails with static linking unless libpthread.a is relinked).
