Merge branch 'develop' of github.com:hpcugent/easybuild-easyconfigs into develop
make OpenMPI sanity check less strict, so they can be built on e.g., OS X (malloc lib seems to depend on external deps?)
explicitely disable OpenIB and UDAPL support for OpenMPI easyconfig with -no-OFED versionsuffix, to avoid that OpenMPI auto-detects the supporting libraries if they're available (refs #40)
Merge pull request #168 from boegel/OpenMPI_fixes

fixes to OpenMPI easyconfigs
