Subject: [PATCH] kconfig: Use KCONFIG_CONFIG instead of .config

When using a custom location for kernel config files this merge config
command fails as it doesn't use the configuration set with
KCONFIG_CONFIG.

Notes:
    Hi,
    
    This patch helps me to merge_configs with config files that are not
    .config (set by using KCONFIG_CONFIG=<PATH>). I am not sure if I break
    something with that change.
    
    I didn't add any stable kernels as this is a kernel config issue and no
    bug in the kernel code itself.
    
    Best,
    Markus
