--try-toolchain with fosscuda/2019a #2975
Description
This works just fine:
eb R-3.5.1-foss-2018b.eb --try-toolchain=fosscuda,2018b -r
whereas this fails:
eb R-3.6.0-foss-2019a.eb --try-toolchain=fosscuda,2019a -r
all with default easyconfigs from the official repository. The error is:
ERROR: Target hierarchy {'lapack_family': 'OpenBLAS', 'name': 'fosscuda', 'blas_family': 'OpenBLAS', 'version': '2019a', 'cuda': True, 'comp_family': 'GCC', 'mpi_family': 'OpenMPI'} should have binutils using GCCcore, can't determine mapping!
Any idea why this doesn't work with the 2019a version of the toolchains anymore?
