If I should file a bug report for this type of thing instead of asking
the mailing list, please advise so I might do the right thing next
time.

I'm unable to successfully execute the bootstrap.sh script for armhf
or aarch64 on an x86_64 host.  Error info below.  I did successfully
execute abuild -r in aports/main/gcc to build the native gcc package.
Any pointers on how to troubleshoot and correct this?
