the spec template has
```
RHJOBS=$RPM_BUILD_NCPUS SPECPACKAGE_NAME=%{name} ./process_configs.sh $OPTS
%{specversion}
```
which looks like it should be ok 🤔
Yep, that'll be fine. The issue isn't the define of RPM_BUILD_NCPUS, but
rather that _smp_mflags has been defined as the *STRING*
'-j${RPM_BUILD_NCPUS}'
Another way to look at this is
```
[prarit@prarit ~]$ echo '-j${RPM_BUILD_NCPUS}'
-j${RPM_BUILD_NCPUS}
[prarit@prarit ~]$ echo "-j${RPM_BUILD_NCPUS}"
-j
[prarit@prarit ~]$
```
