I forget how I learned of it.  Most likely I discovered it by
accident, or I may have gotten it from HJ Lu.  (We worked together at
the time.)

The comma-separated syntax for --target causes essentially the same
effect as a shell loop like this:

for i in i386 i686 x86_64 ; do rpmbuild --target=$i ; done

So, as you would expect in the single-arch case, standard
%ifarch/%ifnarch semantics work correctly in the multi-arch case as
well.
