Subject: [PATCH] pc64: prevent dat.h from getting overwritten by ../pc/dat.h

the rule that was used to copy header files from ../pc
accidently overwrote dat.h when ../pc/dat.h was updated
because it matched on all *.h files that was also found
in ../pc directory. change to exact match on $PCHEADERS
to prevent this.
