Well, I've already found that unsetting of CFLAGS in /etc/make.conf
fixes building. The values of CFLAGS was:

(both 4.10 hosts)

CFLAGS= -O -pipe -march=i586 -mcpu=i686 -mpreferred-stack-boundary=2

(4.8 host with the same problem! hence it isn't special for 4.10)

CFLAGS= -O2 -pipe -mcpu=i686 -march=i486 -mpreferred-stack-boundary=2

The strangeness is seen in libiberty config log diffs for good variant
(without CFLAGS) and bad variant:

All previous tests in libiberty/config.log shows identical results
for both cases! Difference begins only from testing for <sys/file.h>.
And, not all following tests fail.

The third attempt was on 4.10 with the following CFLAGS:

CFLAGS= -O -pipe -march=i686

It bypassed the problematic place. So, is it -mpreferred-stack-boundary?
I'll retest as soon as possible.
