This means that linker has not found a mentioned symbol, i.e. likely
you haven't updated your libc before trying to build ftpd.
In this case you need to act the next order:
1) rebuild&& reinstall libc
2) rebuild&& reinstall ftpd
Oh yes, I just remembered those sweet days I was sitting on HEAD. Each
build was a trial/error process.
And I'm not seeing this when compiling world with stock gcc or on i386.
It looks like rather nasty clang regression.
For me, stable/9 builds just fine with clang (or gcc), and the tinderbox
isn't complaining either. Are you sure you are running buildworld,
which is definitely necessary for this kind of upgrade?

I totally missed this warning when reporting the problem first time.
Version.map for libc contains this function:
FBSD_1.3 {
global:
__FreeBSD_libc_enter_restricted_mode;
} FBSD_1.2;
So the question is mainly about why
/usr/obj/usr/src/tmp/usr/include/unistd.h was ignored in favor of
installed one?
