[PATCH 3/24] ver_linux: gcc.patch

[Alexander Kapshuk]

Using 'awk' here is a bit of an overkill. Should the output of 'gcc
-dumpversion' vary on another disto, or change overtime, it may no longer
be available at field 1, as relied on by the current implementation.
I believe 'sed' offers greater flexibility here in terms of processing
varying output as well as being more light-weight.

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