Yes, this looks as a good solution - better than <threadlib.h>,
which would require explicit patches to all software. Second
necessary part is to change all packages so that no library is ever
explicitly linked against libpthread. This could even be quite
easily accomplishable by hacking libtool to filter -pthread on
final library link.
