Subject: [PATCH] bn_mul.h: workaround for gcc-11.2.0 issues
Currently curl fails 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
curl[7227]: code: 38210020 7c0803a6 4e800020 9421fff0 <7d4d42e6> 7c6c42e6 7d2d42e6 7c0a4840
This is due to a bug in gcc-11.2.0. It is fixed with gcc-11.3.0.
is planed. Instead, remove the code for mpc85xx that is the cause of the
issue.
