I am trying to.
Currently I am stuck with making this work for Yocto 3.4.
Later I may be able to come up with something that works for Yocto master.

rpmrc and the platform specific macros file need changing.

rpm --eval '%{_arch}' also not correct. strace shows that
it looks at the contents of /etc/rpm/platform and then
wants to read /usr/lib/rpm/platform/<platform>/macros
which doesn't exist for e.g. platform=genericx86-64 or
other BSPs.

Also, I am not using multiarch so the default
/usr/lib/rpm/platform/x86_64-linux/macros is not correct
as it tells rpmbuild to use /usr/lib64 as opposed to use /usr/lib.

Not sure what to do with a multiarch Yocto build.
