kconfig: Make localmodconfig handle environment variables
The commit 838a2e55e6a4e9e8a10451ed2ef0f7a08dabdb04
kbuild: migrate all arch to the kconfig mainmenu upgrade
Broke make localmodconfig. The reason was that it added a
environment variable to the kconfig source, which the
streamline_config.pl could not handle.
This patch changes streamline_config.pl to handle kconfig sources
using environment variables in their names.
