Steve Muckle 8954a954c5 tools: add script to verify non-conditional config fragments
Add a script which can be used to verify that the non-conditional
config fragments are consistent, i.e. none of them disappear when
merged into an an allnoconfig.

Usage: ${0##*/} [-h] [-a arches] [-v versions] -k path-to-kernel
Check that the kernel config fragments are consistent with the Kconfig files
in the given kernel versions. This requires an android common kernel repo to
be checked out and made available to this script via the -k option or the
KERNEL_PATH environment variable. Note this script does not verify the
configs in the conditional XML fragments.
