If it doesn't, that's a big big problem. I see, it was introduced earlier today in lib/libc/Makefile: commit ef8030831eccec4e481a1766fc1c67f7cadadac9 Author: emaste <emaste@FreeBSD.org> Date: Fri Sep 21 17:49:37 2018 +0000 libc: require ifunc-capable linker for amd64/i386 We expect to introduce optimized libc routines in the near future, which requires use of a linker that supports ifuncs.
