ptxd_make_world_install_post: Darwin: Edit install name of binaries

This patch should solve the problem that binaries in
$PTXDIST_SYSROOT_HOST/bin must be able to find their libraries in
$PTXDIST_SYSROOT_HOST/lib. On ELF systems that problem is solved
by using rpath. However, rpath doesn't exist (works different) on
Darwin that uses the Mach-O binary format.

After copying the files to $PTXDIST_SYSROOT_HOST, we do following:

 - For every library (lib/*.*.dylib), we change the install name
   from /lib/libfoo.x.dylib to $PTXDIST_SYSROOT_HOST/lib/libfoo.x.dylib.
   That way programs linked against that library can be executed
   immediately, even in the build directory before installation
   to $PTXDIST_SYSROOT_HOST.

   That's the call of "install_name_tool -id".

 - For every library (lib/*.*.dylib) and executable (bin/*), we
   change the install name of dependent libraries to point to
   $PTXDIST_SYSROOT_HOST/lib. The call of "otool -L" lists the
   dependent libraries (like "readelf -d" on ELF systems) and
   the call "install_name_tool -change" changes it. That step
   is necessary because multiple libraries and binaries can be
   built and installed at the same time, so the binary is already
   built before "install_name_tool -id" is invoked.

That way I'm finally able to build host-qemu with host-glib and
host-gettext-dummy (that provides -lintl which host-glib uses).
