freebsd stable - Mar 2019 - ifuncs check flawed?

By default FreeBSD/i386 uses lld as the bootstrap linker (i.e., the
linker used for building the kernel, libraries, and userland binaries)
but still installs GNU ld as /usr/bin/ld on stable/12 due to issues in
the ports tree.

There are a few different ways you could address this:
1. Build either the buildworld or kernel-toolchain targets before make
buildkernel, which will then use the built toolchain including lld.
2. Set LD=ld.lld to explicitly use lld for the kernel link.
3. Build and install world WITH_LLD_IS_LD in src.conf, so that
/usr/bin/ld is lld.

I did this, and it did not work.  I always build the system in the canonical
order:

buildworld
buildkernel
installkernel
installworld

That is why I think the check is flawed!  I am using the lld linker.  It is
present in the snapshot.  The system should be using it, but it immediately
fails due to the aforementioned checks.  That is the bug that I am raising.
