toolchain: gcc: import patch fixing asm machine directive for powerpc
Applications with libmbedtls, e.g. curl, fail on mpc85xx with:
curl[7227]: illegal instruction (4) at b7c94288 nip b7c94288 lr b7c6b528 code 1 in libmbedcrypto.so.2.28.1[b7c3e000+7e000]
curl[7227]: code: 3d7e0000 809e8004 91490000 816b814c 7d6903a6 4e800421 80010024 83c10018

This is due to a bug in gcc-11.2.0. It is fixed with gcc-11.3.0.
Import the patch that is fixing the issue.
