Unfortunately, the patch wasn't enough: while I now could finish a build on
x86_64-pc-linux-gnu, every m2 link test failed like this:
/vol/gcc/bin/gld-2.35:
/var/scratch/gcc/gcc-12.0.0-20210913/5.4.0-gm2/x86_64-pc-linux-gnu/./libgm2/libm2pim/.libs/libm2pim.so:

There are undefined references to
cgetopt_getopt
cgetopt_getopt_long
cgetopt_getopt_long_only
cgetopt_optarg
cgetopt_opterr
cgetopt_optopt
and libm2pim.so has those instead, defined in cgetopt.o:
0000000000020590 T getopt_getopt
00000000000205f0 T getopt_getopt_long
0000000000020650 T getopt_getopt_long_only
00000000000335c8 B getopt_optarg
00000000000335bc B getopt_opterr
00000000000335c0 B getopt_optind
00000000000335b8 B getopt_optopt
The attached new patch fixes this, too, and gives way more reasonable test
results:
