If --tag=CC is not passed to libtool before /home/hch/bin/cgcc, then it
tries to infer the set of compiler settings to use (CC, CXX, F77, ...)
from the compiler name passed.

I don't know the sources in question, but typically you can append
--tag=CC to some $(LIBTOOL) variable or set $(LIBTOOLFLAGS) or so.

Hope that helps.

Cheers,
Ralf
