Fixed it - strace showed me that the compiler was looking for those
libraries in /V1R2M0-efix23 which is the symptom of the relative symlink.

A quick grep and sure enough there was a readlink in the bgclang script.

Adding the -f flag to that readlink fixed it, I can now compile with
only some (apparently innocent) warnings.
