Check gcc version to see if it supports -MM and friends

According to manuals found here: https://gcc.gnu.org/onlinedocs/, GNU
C version 3 and on support the dependency generation options.  We
therefore need to check the gcc version to see if we're going to use
it or makedepend for dependency generation.
