    kbuild: rpm-pkg: do not force -jN in submake · 8a16a070

    The spec file always passes %{?_smp_mflags}, but we have two
    problems here.
    
    [1] "make -jN rpm-pkg" emits the following warning message:
    
        make[2]: warning: -jN forced in submake: disabling jobserver mode.
    
    [2] We can not specify the number of jobs that run in parallel.
        Whether we give -jN or not from the top Makefile, the spec file
        always passes ${?_smp_mflags} to the build commands.
    
    ${?_smp_mflags} will be useful when we run rpmbuild by hand.  When we
    invoke it from Makefile, -jN is propagated down to submake; it should
    not be overridden because we want to respect the number of jobs given
    by the user.  Set _smp_mflags to empty string in this case.
