Stephen, Thank you very much for working on this project!

Checked in for 2.24.

Final version used include/grp-merge.h to remove the PLT entries from
libc.so.6, just standard operating procedure:
~~~
#ifndef _GRP_MERGE_H
#include <grp/grp-merge.h>

libc_hidden_proto (__copy_grp)
libc_hidden_proto (__merge_grp)

#endif /* _GRP_MERGE_H */
~~~
This also removes the need for `#include "grp-merge.h"` or other
forms of ""-based include (since you can now use the standard include
dirs to find the file.
