It seems the problem is even more tricky than "just" bootstrap: AFAICS
the "bootstrap" builds passed, the "bootstrap_profiled" and
"bootstrap_profiled_lto_lean" failed.
So, you need to configure with --enable-bootstrap and build with 'make
profiledbootstrap'.
In addition, the problem occurs on arm targets, as opposed to aarch64,
so the easiest for you is probably to start a container in aarch32
(aka arm) mode on an aarch64 machine (provided its CPU supports that
mode).
Once in the container, you don't need to use --target XXX
--with-arch=YYY configure options.
Good luck,
Christophe
