description:
Restore our local change to remove GNU_STACK program header:

        http://cvsweb.netbsd.org/bsdweb.cgi/src/external/gpl3/gcc/dist/gcc/config/rs6000/rs6000.c#rev1.13

This was removed accidentally when merging GCC10 into our tree.

Note that some firmwares, e.g., Explora, refuse to execute ELF
kernel image if this program header is present.

Now, GCC10 becomes just fine for all three powerpc sub-archs, i.e.,
oea, booke, and ibm4xx, as far as I can see. No regressions are
observed for ATF.

OK mrg
