Johannes is trying to build ports-mgmt/pkg in HardenedBSD
12-CURRENT/amd64, where MK_LLD_IS_LD is default to yes. If you use the
HardenedBSD ports tree, ports-mgmt/pkg is patched to allow a configure
argument to enable SafeStack for pkg(8) and pkg-static(8)
(--enable-safestack).

Reproduction steps:

1. Install HardenedBSD 12-CURRENT/amd64
2. Fetch HardenedBSD's ports tree
3. Attempt to build ports-mgmt/pkg

Thanks,
