Avoid using gensub that FreeBSD awk lacks, use gsub and split those each
of gawk, mawk, and FreeBSD awk provides.

gcc/ChangeLog:

        * config/loongarch/genopts/gen-evolution.awk: Avoid using gensub
        that FreeBSD awk lacks.

Manually tested the script with gawk and FreeBSD awk.  Ok for trunk?

OK.

Thanks!
