kbuild: rpm-pkg: do not force -jN in submake
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. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
