Hwloc dependencies are not resolved at CMake time when static
libwloc.a is detected and in most of these cases link-time
errors will prevent building GROMACS. As it is hard for a user to know
how to solve such cryptic errors and hwloc is not a required dependency,
we turn off hwloc support when a static lib is detected. The user can
override this on the cmake command line.
