FWIW, I hade the same problem (amd64 host, amiga target) with a completely 
new and empty objdir and sources as of this morning, CET.

A quick test suggest this will happen if ${ACTIVE_CC} simply isn't defined 
when the expression is evaluated, effectively yielding:

defined(7) && 7 == 7 && == "gcc"
