The problem with the linker script grammar is that "foo *" and "foo*"
can't both tokenize to IDENTIFIER STAR, since in the context of a
wildcard expression they mean different things. It certainly can be
dealt with by making the tokens whitespace sensitive or doing post
processing, but it is certainly not a nice grammar.
