@pkubaj Are you able to test on a gcc-based arch? I removed some workarounds that I believe are now cruft, but can't easily test.

GCC architectures are completely broken and can't build ports-mgmt/pkg:

===>  Building for pkg-1.20.7
cc -Wall -Wextra -std=gnu11 -D_GNU_SOURCE=1 -MT blake2b-ref.o -MD -MP -MF blake2b-ref.Tpo -o blake2b-ref.o -c -O2 -pipe  -Wno-error -fstack-protector-strong -fno-strict-aliasing   -Werror=implicit-function-declaration -Werror=return-type -I/wrkdirs/usr/ports/ports-mgmt/pkg/work/pkg-1.20.7/compat -O3 blake2b-ref.c
cc1: error: unrecognized command line option "-std=gnu11"
*** Error code 1

Ok, thanks for letting me know. In the meantime, I tested with USE_GCC=yes and all was fine. If you can start building packages on POWER again, we can address any issues then.
