Uoti Urpala e786c70de9 build: change version number generation
Force Makefile to always run version.sh to potentially regenerate
version.h. Drop compiler version and 'git-' prefix from version
number. Match only git tags starting 'v'+number when generating
version number; leave the 'v' out from the result.
