[PATCH] powerpc: Suppress 'executable stack' warning at link
Following warning is observed at link.
powerpc-linux-ld.bfd: warning: arch/powerpc/lib/reloc.o: missing .note.GNU-stack section implies executable stack powerpc-linux-ld.bfd: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
Add -zexecstack to KBUILD_LDFLAGS in order to suppress this warning.

This has been addressed in -next with: commit 57450d8661b3ec2e6b6f1d938e59f426cafb06d2 Author: Tom Rini trini@konsulko.com Date: Tue Feb 14 15:09:31 2023 -0500
Makefile: Link with -z noexectack
When moving to gcc-12.2 we started trying to quiet some of the new linker warnings, that are not relevant to us. However, a misunderstanding of the mechanics at play meant that I intentionally omitted passing -z noexecstack to the linker, when we do need to. Add this flag and in turn remove warnings from the linker.

I didn't put this in master as (as far as I know) we're merely telling the toolchain we're being intentional, and not changing the behavior.
