opc-file-path

[Steve Woloschek]

I am working on a port of a new processor core and have run into an
issue when running desc-cpu.c[c|h].

./desc-cpu.scm:1038:32: In expression (opc-file-path):
./desc-cpu.scm:1038:32: Unbound variable: opc-file-path

It appears the scripts assume there is an '[cpu].opc' file. I noticed
that several processors in the /cpu directory do not have a .opc file.

Any thoughts on how to get around this feature?

Thanks in advance for you help.
