Show-stopper samba-4.7.0rc3 on AIX when using xlc

Been working on packaging SAMBA for AIX the last 24 hours. Via the bug 
reports I saw some patches that have been applied to SAMBA-4.7 (but not 
in the 4.4.15.+ I guess) - so started a test of the rc as well.

It stops almost immediately - with a bad compiler flag -

WAF_MAKE=1 python ./buildtools/bin/waf build

If I cut/paste the command but also remove the bad flag 
(-Wno-format-zero-length) the compile is successful. But only for one file.

With 'waf' I have no idea where I should be looking for this "forced" 
gcc (guessing) flag being applied everywhere.

Hope this helps - In a later mail I'll give a report on what I did to 
get 4.4.15 to build.
