Josh Hunt b925dbfe3c kbuild: fix 'make rpm' when CONFIG_LOCALVERSION_AUTO=y and using SCM tree
Running 'make rpm' fails when CONFIG_LOCALVERSION_AUTO=y and using a kernel source
tree under SCM.  This is due to KERNELRELEASE being different when the initial make
is run and when make is run from rpmbuild.

mkspec creates kernel.spec using KERNELRELEASE:

<mkspec>
echo "%files"
echo '%defattr (-, root, root)'
echo "%dir /lib/modules"
echo "/lib/modules/$KERNELRELEASE"
echo "/lib/firmware"
echo "/boot/*"
echo ""
</mkspec>

When CONFIG_LOCALVERSION_AUTO=y scripts/setlocalversion is called and grabs any
additional version info from SCM.  Next, the srctree is tarred up and SCM
information is excluded.

rpmbuild reruns make and in the process generates a new include/config/kernel.release
and thus a new KERNELRELEASE.  However this time the SCM information is gone so
KERNELRELEASE no longer has the additional version information.  When "make modules_install"
runs, it uses the new KERNELRELEASE value to determine where to install the modules.
This conflicts with where the spec file assumes they are going because of the
mis-matching KERNELRELEASE versions.

I have tested this patch on git -tip, Linus' git tree, and the kernel.org tar files, both
with and without CONFIG_LOCALVERSION_AUTO=y.

# Makefile for the different targets used to generate full packages of a kernel
# It uses the generic clean infrastructure of kbuild
# RPM target
# ---------------------------------------------------------------------------
# The rpm target generates two rpm files:
# /usr/src/packages/SRPMS/kernel-2.6.7rc2-1.src.rpm
# /usr/src/packages/RPMS/i386/kernel-2.6.7rc2-1.<arch>.rpm
# The src.rpm files includes all source for the kernel being built
# The <arch>.rpm includes kernel configuration, modules etc.
#
# Process to create the rpm files
# a) clean the kernel
# b) Generate .spec file
# c) Build a tar ball, using symlink to make kernel version
# first entry in the path
# d) and pack the result to a tar.gz file
# e) generate the rpm files, based on kernel.spec
# - Use /. to avoid tar packing just the symlink
# Do we have rpmbuild, otherwise fall back to the older rpm
