only force symbol lookups with local variables on hppa

[Mike Frysinger <vapier at gentoo dot org>]

as a follow up to the slow script thread:
http://sources.redhat.com/ml/gdb/2006-08/msg00099.html

attached patch will change the behavior so symbols with dollar signs in them 
($) are only looked up when a specific arch says to do so (with hppa being 
the only one at the moment)
