toolchain/gcc: remove upstreamed patch, add backport

This patch has been upstream since GCC 10.
Dragan Mladjenovic (2):
      Emit .note.GNU-stack for soft-float linux targets.
      Emit .note.GNU-stack for hard-float linux targets.

Link: https://gcc.gnu.org/g:a3c1e1f2ff88
Link: https://gcc.gnu.org/g:54b3d52c3cca

Add backport patch to define TARGET_LIBC_GNUSTACK on musl to add
.note.GNU-stack on hard-float MIPS targets.

Link: https://gcc.gnu.org/g:25abbb924968

The net effect should be the exact same functionality while following
upstream code instead of a custom outdated patch.

-I talked to Andrew about what files he changed in GCC and created and
-tested this new patch.  Andrew also mentioned changing some assembly
-files in glibc but I don't see any use of '.section .note.GNU-stack' in
-any assembly files in glibc (for any platform) so I wasn't planning on
-creating a glibc to add them to mips glibc assembly language files.
-
-OK to check in this patch?
