infra/pkg-kconfig: require an non-empty KCONFIG_FILE
Currently, we only check that the variable is defined, which is not enough since we really want it to be non-empty. We however can't check it points to an existing file, because the package might well not be extracted yet, and we may use an internal defconfig. If that file does not eventually exist, there will be a failure down the road at build time when we try to copy it... Signed-off-by: "Yann E.
