Ah OK, I didn't notice that auto.conf should be generated in build
directory (in my case build dir == source dir).

I just noticed broken kernel module builds in gentoo, because local
version is also checked without changing CWD
KV_LOCAL="${KV_LOCAL}$(sh ${KV_DIR}/scripts/setlocalversion ${KV_DIR})"
in get_version()
http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/eclass/linux-info.eclass?view=markup

So if scripts/* behavior is not considered as "API" then it should be
fixed in gentoo eclass. It also appends LOCALVERSION twice now, because
first appends LOCALVERSION from config and then calls setlocalversion
also returning it at the beginning.

Thanks
