so based on this long discussions the final proposal is:

diff --git a/mk/userland-cflags.mk b/mk/userland-cflags.mk
+WERROR_CFLAGS?=-Werror -Wno-missing-field-initializers

As long as we want to support CentOS6 or older compilers we should add this.  
I know it works on CentOS 6 and clang. Currently CentOS 6 is broken, Travis 
tests, due to the fowling error. 

Tumo's work around is WERROR_CFLAGS=''  He is pushing this for travis, 
CentOS 6 testing too. I hopping there is a better fix.

not likely. Did you test on CentOS 6? The error only show up on CentOS. As I 
recollect it started showing up recently, 2019, and on IRC the comment was 
too old compiler, ignore it. Then I thought something for Hugh to ponder!
