kconfig: fix oldconfig to generate .config.cmd
Since the recent update of Kconfig to the Kconfig infrastructure found in 2.6.30 kernels, make oldconfig was broken because it didn't generate the .config.cmd file. This is done by a call to the conf_write_autoconf() function. Moreover, this process was also broken because the conf_get_autoconfig_name() function was reading the environment variable BUILDROOT_AUTOCONF while the main Makefile is passing it as KCONFIG_AUTOCONFIG. We also remove the fallback on "$(BR2_DEPENDS_DIR)/config/auto.conf" since we are not able to expand BR2_DEPENDS_DIR at this point. Therefore, the KCONFIG_AUTOCONFIG envionment variable *must* be set. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
