Synched current a few minutes ago, tried to build again, got another
error, looks the same:

Please submit a full bug report,
with preprocessed source if appropriate.
See <http://www.NetBSD.org/support/send-pr.html> for instructions.

The good news is I can complete the same build on my raspberry pi.
I'll try it on a virtual machine that is amd64 based as well.
