I'll take a look later if I find time.

Dunno, that's not what I'm looking for in this particular case; test-
building for i386 and i686 and watching the build log whether our
optflags are being honored is something I do for most packages anyway.
In addition to sometimes catching upstream configure/makefile bogosity,
compiler bugs etc, it helps people who actually want to see if using
different optflags makes a difference wrt. runtime performance of the
package.
