Detailed test report on re-building all easyconfigs that use foss/2018b as toolchain with the proposed foss/2019a instead is available at https://gist.github.com/boegel/68b542fa564fd370e8b0e7710a320f6f .

Compilation failed for a handful of easyconfigs with cryptic errors (to be figured out), but I don't think any of these should block us from going forward with the current foss/2019a definition (and this was not contested during the last EasyBuild conf call, see https://github.com/easybuilders/easybuild/wiki/Conference-call-notes-20190123#test-report-for-proposed-2019a-common-toolchains).

Summary: 234 successfully installed easyconfigs using foss/2019a (+ 102 more with GCCcore/8.2.0 subtoolchain) vs 4+3 failed installations.
