openssl: OpenSSL 3.2.0 build fails on 32bit PowerPC macs running OS X

On a 32bit (ppc7450) PowerPC Mac (iBook G4) running Mac OS X 10.5 (darwin 9), the build of OpenSSL 3.2.0 fails due to the use of 64bit instructions in crypto/aes/aesp8-ppc.s which I guess is for POWER8 but targets ppc970 (G5) which is 64bit.

I guess we now need to state no-asm on such systems?

Invoking the build with

perl Configure --prefix=/tmp/openssl3 no-ssl3 no-ssl3-method no-zlib darwin-ppc-cc

Build eventually fails with
