Fix: 

make sure CFLAGS either empty or has some -Ox options before buildworld.
But compile should be successful even with CFLAGS="".
How-To-Repeat: /etc/make.conf has a line "CFLAGS="

My CFLAGS when the problem occurred was set in /etc/make.conf as
CFLAGS=-I/usr/local/include

I confirm that after deleting and re-downloading the sources this problem still
exists.

Please investigate.

State Changed
From-To: open->closed

It's documented in make.conf(5) that we don't support optimization 
levels other than -O and -O2, and specifying an empty CFLAGS is 
equivalent to -O0, which breaks the i386 build in this case.
