FYI: I tried to build 13.1-BETA2 with a gcc9 xtoolchain and got:

--- all_subdir_stand/efi/gptboot ---
. . .
/local/bin/x86_64-unknown-freebsd13.0-ld: gptboot.sym.full: error: PHDR segment not covered by LOAD segment
collect2: error: ld returned 1 exit status


So I tried continuing using WITHOUT_BOOT= and the next stopping
points were:

With that I stopped the experiments.
