kconfig: search for a config to base the local(mod|yes)config on
Instead of using the .config in the local directory. This patch
changes streamline_config.pl to search various locations for a config.
Here's the list and order of search:
/proc/config.gz
/boot/vmlinuz-`uname -r`
vmlinux # local to the directory
/lib/modules/`uname -r`/kernel/kernel/configs.ko
kernel/configs.ko
kernel/configs.o
.config
Once it finds a file that contains a config (it checks if the binary
objects have configs first) it then uses it to create the .config
with minimum modules needed.
