Calling 'awk' more then once is redundant. The output of 'make --version'
already has the data we are after, why not utilise it.
The proposed implementation uses 'sed' to utilise the data output
modifying the white space formatting only.
Tested on:
Gentoo Linux
Debian 6.0.10
Oracle Linux Server release 7.1
Arch Linux
openSuSE 13.2
