compiler-gcc: improve version error
As Kees suggests, doing so provides developers with two useful pieces of
information:
- The kernel build was attempting to use GCC.
(Maybe they accidentally poked the wrong configs in a CI.)
- They need 4.9 or better.
("Upgrade to what version?" doesn't need to be dug out of documentation,
headers, etc.)
