Given the current state of OS X compilers, the original fails_with
behavior is becoming less useful, mostly resulting in build failures
each time the compiler is updated. So make the following changes:
When a build is specified, we retain the old behavior: switch compilers
if the available compiler is <= the build, don't switch if it is > the
build.
When no build is specified, unconditionally switch compilers, and don't
output the advice message. This allows us to mark formulae as
perpetually failing, avoiding the need to update formulae each time a
new compiler build is made available.
As a bonus, this makes the logic much easier to reason about.

SimGrid is a toolkit that provides core functionalities for the
simulation of distributed applications in heterogeneous distributed
environments. The specific goal of the project is to facilitate research
in the area of parallel and distributed large scale systems, such as
Grids, P2P systems and clouds. Its use cases encompass heuristic
evaluation, application prototyping or even real application development
and tuning. (from the project homepage http://simgrid.gforge.inria.fr/)
