Subject: merge_config.sh: Allow to define config prefix
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=2cd3faf87d2d8f6123adf34741b9a7b98828a76f;p=openwrt%2Fstaging%2Fblogic.git

merge_config.sh: Allow to define config prefix

with CONFIG_ environment variable.

merge_config.sh uses CONFIG_ which is used in kernel and other projects.
There are some projects which use kconfig with different prefixes (e.g.
buildroot: BR2_ prefix). CONFIG_ variable is already used for this
purpose in kconfig binary (scripts/kconfig/lkc.h), let's use the same
rule for in merge_config.sh.
