I think that it may only be necessary to create a small .so containing
the new syscall stubs. Then only the new libpthread would be needed.
Maybe ld.so.conf could get the library loaded, alternatively it could
be built with a .SONAME matching that of libpthread, with a .NEEDED
entry to pull in the new libpthread itself.
