Subject: [PATCH 7/24] scripts/ver_linux: module-init-tools.patch

The current implementation relies on 'depmod' to be available in the
PATH. It also expects the version number to be found in the last field
as seen by 'awk'. Should the output format be different, this approach
would no longer be reliable.

The proposed implementation locates 'depmod', and uses 'sed' as a more
flexible tool to handle varying output formats.

Tested on:
Gentoo Linux
Debian 6.0.10
Oracle Linux Server release 7.1
Arch Linux
openSuSE 13.2
