Hi Marc,

The error message you are seeing originates from the GHDL configure
command. It seems like GHDL support for LLVM 8 was added pretty
recently (see https://github.com/ghdl/ghdl/commit/7328eae022b0b85c2071ea4d4aaad0c7a97ca436#diff-e2d5a00791bce9a01f99bc6fd613a39d)
so my best tips would be to make sure you have the latest GHDL
version. This does not seem to be an LLVM issue.

Best Regards
David
