Subject: [PATCH] ver_linux: libc.patch

The current implementation has been found not to work across all distros.

The proposed implementation relies on 'sed' to both output the string
'Linux C Library' as well as to open '/proc/self/maps' without having
to use output redirection.

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