Example case, first without option:

alanc@~/EasyBuild_Git/easybuild-framework(allow_ignoring_versionsuffix)$ eb --try-toolchain=intel,2019b --robot --experimental --try-update-deps -D  --disable-minimal-toolchains BioPerl-1.7.2-intel-2018b-Perl-5.28.0.eb
== temporary log file in case of crash /tmp/eb-lS5RRf/easybuild-FgltLZ.log
