linux-backports manually generates its autoconf.h header, which needs a
.config file.
Using a pre- or post-configure hook does not really work, because
generating that file touches the .config, and thus our .stamp files ar
enot longer properly time-ordered and running a subsequent make would
incorrectly believe it has to rebuild linux-backports.
So, even though this is not a fixup proper, we generate that file from
the _KCONFIG_FIXUP_CMDS to ensure the stampt file is created after we
touch .config.
