Subject: Fix whole static lib handling of duplicate names.

If LOCAL_WHOLE_STATIC_LIBRARIES contains a library that has
two files that have the same name but are in different
directories, only the first gets included.

This fix detects this case, and uses the m option to ar to force the
duplicate object to the end of the archive. After this, using the p
option gets the correct object file.
