Cross-building (bin)rpm-pkg fails on several architectures.
For example, 'make ARCH=arm binrpm-pkg' fails like follows:
sh ./scripts/package/mkspec prebuilt > ./binkernel.spec
rpmbuild --define "_builddir ." --target \
arm -bb ./binkernel.spec
Building target platforms: arm
Building for target arm

By default, 'buildroot' contains %{_arch} (see /usr/lib/rpm/macros).
_arch is generally defined in /usr/lib/rpm/platforms/*/macros, where
the platform sub-directory is specified by --target= option for cross
builds.
If the given arch does not exist, %{_arch} is not expanded.
In the example above, --target=arm is passed to rpmbuild, but
/usr/lib/rpm/platforms/arm-linux/ does not exist.
The '%' character in the path confuses GNU make and rpmbuild.
The same occurs for such architectures as csky, microblaze, nios2, etc.
Define _arch if it has not been defined.
