Handle STT_COMMON symbols too. Following binutils release

will set the type of common symbols to STT_COMMON
instead of STT_OBJECTS, so the dynamic linker needs
to handle this type os symbols too.
Same changes have been added to glibc (See: bugzilla #5104).
This patch ensures the uclibc will work with later bintuils.
