Introduce %_smp_build_ncpus macro

Browse Source 
This macro offers %{_smp_mflags}, but without the -j prefix, to signify
the configured number of processor cores to use.
We can use this to pass that number to utilities that do not understand
the -j number syntax, for example:
`cmake --build %_cmake__builddir --verbose --parallel %_smp_build_ncpus'

The name was picked to be compatible with RH:
https://github.com/rpm-software-management/rpm/blob/rpm-4.16.1.3/platform.in#L51
We preserve ALT semantics though.
