kconfig: have extract-ikconfig read ELF files
It would be nice to use extract-ikconfig to find the congfig.gz in either vmlinux (not vmlinuz) or configs.ko. This patch changes the script to also be able to read ELF files directly. [ Impact: find config.gz in vmlinux and configs.ko ] Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
