crossgcc/gnat.patch: Add additional gnatlib object files

Newer host versions of gnatbind miss these when building the cross
gnat1 and gnatbind.

Tested with the following host compilers with and without bootstrapping
that the resulting coreboot images of three boards stay the same:
* GCC 4.9.2 (Debian)
* GCC 6.3 (Debian)
* GCC 7.4 (Debian)
* GCC 8.3 (Debian)
* GCC 9.4 (Debian)
* GCC 10.2 (Debian)
* GCC 12.1 (ArchLinux)
