> Almost, but not quite, correct. We cannot change the autoconf-config.guess file due to license restrictions (the license allows redistribution, not modifications). Instead we have the config.guess file which "wraps" autoconf-config.guess and makes pre-/post-call modifications to work around limitations in the autoconf original file. So you need to check there if you are getting incorrect results back and adjust it in that case. See the already existing clauses in that file.
I have updated PR and moved this logic to make/autoconf/build-aux/config.guess
It's pretty similar to i386 -> x86_64 fix-up on macos_intel
