building head -r338675 with devel/amd64-gcc: /usr/local/x86_64-unknown-freebsd12.0/bin/ld: warning: -z ifunc-noplt ignored

Hmmm, what does make -V LINKER_TYPE and make -V LINKER_FEATURES say?

They look good for me, but the only way you get this error is if they are
wrong.

Although from your typescript, I see:

===> lib/libc (cleandir)
make[4]: "/usr/home/bcran/workspace/freebsd/lib/libc/Makefile" line 26:
amd64 libc requires linker ifunc support

which tells me that we need to exclude all the non-build targets from this
check.... This will use the HOST linker rather than the TARGET linker.

So something like:

diff --git a/lib/libc/Makefile b/lib/libc/Makefile
index a1ce123c0f33..11575e1cabff 100644
--- a/lib/libc/Makefile
+++ b/lib/libc/Makefile
@@ -21,10 +21,12 @@ LIBC_ARCH=${MACHINE_ARCH}
 LIBC_ARCH=${MACHINE_CPUARCH}
 .endif

+.if build(all)
 .if (${LIBC_ARCH} == amd64 || ${LIBC_ARCH} == i386) && \
     defined(LINKER_FEATURES) && ${LINKER_FEATURES:Mifunc} == ""
 .error ${LIBC_ARCH} libc requires linker ifunc support
 .endif
+.endif

 # All library objects contain FreeBSD revision strings by default; they
may be
 # excluded as a space-saving measure.  To produce a library that does

may be needed, but the problem may be related to caching these values from
the host as well, even though we rebuild them...
