There was a big merge of changes to the runtime (and some consequent
changes to the implementation of the Basis Library), but I wouldn't have
expected this to affect linking behavior.

I note that if you compile with -keep o and then replicate the gcc linking
line at your shell, then the linking succeeds; so, it looks like the call
to gcc is being messed up somehow, probably in the way arguments are being
passed. I'll investigate.
