The fixes here are just patches for the autoconf "config.sub" files of 
these 3 projects.

The problem with these projets (isl/mpc/mfpr) is that they have not had 
any releases for 2+ years, before the M1.

#find build . -name config.sub | xargs grep '^timestamp='


The other projects in the tree using autoconf that have been released in 
2021+ compile fine on the M1.

The 3 projects in questions have nothing special to do to get M1 support 
except release a new version with up-to-date autoconf stuff.
