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

[Mark Millard]

In looking into another report about using devel/amd64-gcc to buld
head I tried a build of -r338675 ( with WERROR= ). It got:

--- kernel.full ---
linking kernel.full
/usr/local/x86_64-unknown-freebsd12.0/bin/ld: warning: -z ifunc-noplt ignored.

--------------------------------------------------------------
>>> Kernel build for GENERIC-NODBG completed on Thu Sep 20 18:38:29 PDT 2018

Question:

Is ignoring "-z ifunc-noplt" a problem for using what
is built?
