Yes, rpmbuild --target is known not work, i.e. rpm is known not to support cross building - Which had been the initial motivation for --target.
Well I never tried any built-in support for cross building in rpm, because I never found out about it, but you can cross build things fine with rpm by shoving the appropriate things (usually just host) down configure's throat. I found you had to override these as well (crosspath is my convention that is used in the specfiles too), eg
%crosspath /path/to/cross/compiler/br3/bin %__strip %crosspath/arm-linux-strip %__objdump %crosspath/arm-linux-objdumpHow you generalize it to being able to build any arch on demand I did not try yet, maybe you can define a var on rpmbuild commandline like %crossarch and define everything dependent on the arch with that embedded in the paths, eg %crosspath /path/to/cross/compilers/%crossarch/br3/bin
