From 2a291fc315b6aec2f209aa44da90515ddd4f89d0 Mon Sep 17 00:00:00 2001

Subject: kbuild: rpm-pkg: introduce %{with_devel} switch to select devel
 package

scripts/package/mkspec preprocesses the spec file by sed, but it is
unreadable. This commit removes the last portion of the sed scripting.

Remove the $S$M prefixes from the conditionally generated lines.
Instead, surround the code with %if %{with_devel} ... %endif.
