 That's alright. I am unemployed since a few weeks, and in February
 retirement is awaiting me…

 Ken, my Tiger runs on a PowerPC G4 processor. And when I use
 /opt/local/bin/as, configure (from manually building GCC 10.4 unpatched)
 tells me in stages 1 and 2 (hasn't come further yet) when performing its
 work in ./gcc:

 {{{
 checking assembler for .balign and .p2align... yes
 }}}

 instead of

 {{{
 checking assembler for .balign and .p2align... no
 }}}

 because /opt/local/bin/as is almost up-to-date:

 {{{
 -rw-r--r-- fredzlotnick/staff  26792 2020-02-28 19:02
 cctools-949.0.1/as/as.c
 }}}

 (According to my calendar.)

 OK, when this only works on PPC, then a patch is of course necessary in
 order to not discriminate intel CPUs.

 Besides, my effort is to find faults in the configure scripts. I reported
 them from the GCC 10.3 bootstrap builds and was asked to better report
 those from the recent version.

 To me it seems an improvement to start building GCC 10 with modern tools.
 In the end the installed software will be built by GCC 10 and not the
 system's tools. Maybe it's worth to create a variant for gcc10-bootstrap
 that just uses the system's installations of gmp, isl, mpfr, and mpc in
 order to save some disk space (there aren't so many 2,5" disks with PATA
 interface and more than 100 GB capacity):

 Hard links created by me. (Could be cleaner, and closer to perfection, as
 I see now – by using more up-to-date compression.)
