According to
http://www.einval.com/debian/strace/build-logs/mips/2016-07-25-020504-log-minkus-SUCCESS.txt
and
http://www.einval.com/debian/strace/build-logs/mipsel/2016-07-25-020436-log-etler-SUCCESS.txt
there are no compilation warnings on these architectures.

Looks like either gcc or kernel headers (or both) is not recent enough
to build strace without warnings.

You didn't have to attach the whole log when the relevant part is
relatively small:

This is a known issue, gcc used to complain about NLMSG_OK macro, which
is indeed poorly defined.

Newer versions of gcc no longer complain about this.
