www/firefox build failure

[Paul Goyette <paul%whooppee.com@localhost>]

Build host is NetBSD amd64 9.99.99 from 2022-09-09.  All dependencies
have been rebuilt from scratch in an initially-empty chroot sandbox
created by pkgtools/mksandbox.

The build fails quite early on.  Finding the actual error is hard, but
I think this is (part of) it:
