PR24411, Division is not accepted in MEMORY length expression 

Let's hope no one has section names starting with '/' in scripts.  If
they do, this change to fix parsing of '/' in expressiongs will break
their project.

	PR 24411
	ldlex.l (SYMBOLNAMECHAR1): Don't match '/'.
	(<EXPRESSION>"/DISCARD/"): New.
