is it possible to skip a noarch subpackage on certains archs (arm)

[Zbigniew Jędrzejewski-Szmek]

Hi,

I have a package (a C++ library), which generated doxygen
documentation during build. The documentation lands in a noarch -doc
subpackage, the rest in the main package or in subpackages, all
arch-ed.  The problem is that generating the documentation takes
forever (6+ hours) on arm. The arch-ed parts build fairly
quickly. Would it be possible to use %ifarch or equivalent to only
build the (slow) -doc subpackage on x86_64 or i686 archs? Would arm
then get the noarch subpackage from other archs?
