Subject[PATCH 5/9] kbuild: rpm-pkg: fix build error when CONFIG_MODULES is disabled
Date
When CONFIG_MODULES is disabled, make rpm-pkg / binrpm-pkg fails
with the following message:

The present kernel configuration has modules disabled.
Type 'make config' and enable loadable module support.
Then build a kernel with module support enabled.

Do not install modules in the case. Also, omit the devel package.
