Builds fine on FreeBSD package cluster e.g.,

http://beefy9.nyi.freebsd.org/data/latest-per-pkg/wayland/1.16.0_1/113amd64-default.log
http://beefy10.nyi.freebsd.org/data/latest-per-pkg/wayland/1.16.0_1/113i386-default.log
http://beefy6.nyi.freebsd.org/data/latest-per-pkg/wayland/1.16.0_1/120amd64-default.log
http://beefy5.nyi.freebsd.org/data/latest-per-pkg/wayland/1.16.0_1/120i386-default.log

libwayland is required by Mesa as used by Xorg via Xwayland, Xserver (DRI API).

Maybe HardenedBSD changed LOCALBASE recently. If so bsd.port.mk may
detect libffi.so from /usr/local but pkg-config look under /Packages/hbsd.
