[easybuild] Difference between toolchains foss and goolf?

[Ole Holm Nielsen]

Dear EasyBuild users,

We're starting work on updating the easybuild-easyconfigs for our 
simulation packages ASE and GPAW in order to make the latest updates 
available to the EasyBuild community and on our Linux cluster.

We'll be needing a toolchain including modern versions of GCC, OpenMPI, 
OpenBLAS/LAPACK, ScaLAPACK(/BLACS), FFTW.  The target platform will be 
CentOS 7.2 which supplies GCC 4.8.5.

Question: Which of the two seemingly identical toolchains "foss" and 
"goolf" in the official toolchain list should we be using?

Thanks,
Ole
