powerpc: suppress some linker warnings in recent linker versions
This is a follow on from commit
0d362be5b142 ("Makefile: link with -z noexecstack --no-warn-rwx-segments")
for arch/powerpc/boot to address wanrings like:
ld: warning: opal-calls.o: missing .note.GNU-stack section implies executable stack
ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
ld: warning: arch/powerpc/boot/zImage.epapr has a LOAD segment with RWX permissions
This fixes issue https://github.com/linuxppc/issues/issues/417
