Ehh, two things:

- This implements the opposite logic of what the commit message says
  (E.G. adds flex/bison if the version ISN'T 4.2/4.3/4.4)

- It overrides GCC_HOST_PREREQ instead of appending to it even though
  the line just above already appends something.

It isn't clear to me what the gcc version logic should be, and if it is
somehow related to ARC - I don't recall any autobuilder failures
regarding missing flex/bison.
