Subject: [PATCH] streamline_config.pl: handle also ${CONFIG_FOO}

From: Jiri Slaby <jslaby@...e.cz>

streamline_config.pl currently searches for CONFIG options in Kconfig
files as $(CONFIG_FOO). But some Kconfigs (e.g. thunderbolt) use
${CONFIG_FOO}. So fix up the regex to accept both.

This fixes:
$ make LSMOD=`pwd/`/lsmod localmodconfig
using config: '.config'
thunderbolt config not found!!
