I don't believe that you can do this with in a single pass build. 
However, with creative use of BuildArch, and ExclusiveArch, you should
be able to do this in a couple of passes.  So, you'd run 'rpm -bb' and
it would generate app-pkg_a-1-1.i386.rpm and app-pkg_b-1-1.i386.rpm, and
then you'd run 'rpm -bb --target=i686' and it would generate
app-pkg_c-1-1.i686.rpm.  Not particularly pretty, but it should work to
do what you want.  I don't know of any "good" examples on doing this
though.  Read MaxRPM, I guess.  :)
