The issue is flags like ARCH can be passed to make via environment variable
or at command line by passing "ARCH=" argument to make file. The former case
works fine if used with merge_config but the later case would not work and
resulting config file from merge_config is useless.
I hit this issue when I started using config fragments on arm64 bit platform
and I usually pass ARCH at the make command line.
As it is common for users like me to pass ARCH variable in command line,
providing such flexiblity in merge_config makes more sense.
This patch adds support to pass arguments to make file, without this patch the
user has to set the enviroment variables which is not explicit.
