gcc -dumpversion has only MAJOR.MINOR, not MAJOR.MINOR.PATCHLEVEL
At least, for gcc 4.7 on Debian. OTOH, gcc --version outputs
(on its first line)
gcc-4.7.real (Debian 4.7.2-5) 4.7.2
so use that. Hopefully will work across systems & distros.
(gcc-4.7.real is probably just argv[0],
because diversion from hardening-wrapper)
