Here goes :).  The first three patches are unrelated fixes.  Patch 4 implements
"make localmodconfig MODULES_LIST=lsmod.out".

1. kconfig: streamline_config.pl: "use strict" (and fix the errors)
2. kconfig: streamline_config.pl: fix out-of-tree builds
3. kconfig: streamline_config.pl: add handling for "if" statements in Kconfig
4. kconfig: streamline_config.pl: optionally accept lsmod output
