I don't see why pkg is trying to build lld?  It's just a package
management tool.  Or are you building some sort of jail, e.g. in
poudriere?

For me, it's easiest to have a reproduction scenario where I can build
either FreeBSD head or HardenedBSD master, with some specific src.conf
settings.  So maybe MK_LLD_IS_LD would cause this problem?
