Subject: [PATCH v2 4/5] kbuild: srcrpm-pkg: create source package without cleaning
If you run 'make (src)rpm-pkg', all objects are lost due to 'make clean',
which makes the incremental builds impossible.
Instead of cleaning, pass the exclude list to tar's --exclude-from
option.
Previously, the .config was contained in the source tarball.
With this commit, the source rpm consists of separate linux.tar.gz
and .config.
Remove stale comments. Now, 'make (src)rpm-pkg' works with O= option.

-# The <arch>.rpm includes kernel configuration, modules etc.

-# c) Build a tar ball, using symlink to make kernel version

-# d) and pack the result to a tar.gz file
-# e) generate the rpm files, based on kernel.spec
