Commas have to be "top-level" tokens. The arguments to a function are
parsed BEFORE they are expanded, so the comma separating an argument
cannot appear inside a variable.
Assuming the suffix is always the same (.o), why not just use:
SRCFILES := foo.c bar.c baz.cpp
OBJFILES := $(addsuffix .o,$(basename $(SRCFILES))
