This is indeed how it is done in Debian, roms are built in separate packages.
There is also the complication of building ROMs for non-native archs.
Say building openbios-sparc when building qemu on x86, or vgabios when
building qemu on ppc. Then you need a crosscompiler at hand.

While it is not useful for distributions, making it possible to build roms as
part of qemu build process is still usefull for people hacking on qemu.
