Please note, this actually required more changes than this, and also, based on the fact gcc now appears to have fallen into the rapid major version inflation game that firefox and chrome have made popular, I committed a fix that future proofs up to 2 major version digits, which based on the silly pattern we see from chrome and firefox, should cover us for a few years ;)

Thanks for noticing this, I'm not merging this pull but check the new version for the full fix. Note that I gave up on trying to do specific version tests, and now simply look for a valid number in the format xx.yy or x.yy or xx.y

grep -Eio 'gcc[[:space:]]*version[[:space:]]*[0-9]{1,2}\.[0-9]{1,2}' /proc/version | grep -Eo '[0-9]{1,2}\.[0-9]{1,2}'
7.3

Note that this fix would continue to work when gcc hits version 10.xx
