SH provides a pt-initfini.c, so use that instead of
libpthread/nptl/sysdeps/pthread/pt-initfini.c

This prevents:
  libpthread/nptl/sysdeps/pthread/crti.S: Assembler messages:
  libpthread/nptl/sysdeps/pthread/crti.S:25: Error: pcrel too far
  libpthread/nptl/sysdeps/pthread/crti.S:26: Error: pcrel too far
  libpthread/nptl/sysdeps/pthread/crti.S:28: Error: pcrel too far
  libpthread/nptl/sysdeps/pthread/crti.S:53: Error: pcrel too far
  libpthread/nptl/sysdeps/pthread/crti.S:56: Error: pcrel too far
  make[1]: *** [libpthread/nptl/sysdeps/pthread/crti.o] Error 1

There is probably a better way to handle this... but since 9381d622e2411a35a5fd7
I do not want to even try.
