Specify pattern rules in addition to suffix rules

Specify pattern rules in addition to suffix rules

A few makefiles specify an old-style suffix rule, such as:

  .c.o:
          $(AFS_CCRULE) $<

Not all makes seem to interpret these rules correctly (such as Solaris
/usr/xpg4/bin/make). Since it is easy to do so, specify pattern-based
rules along with these, like so:

  %.o: %.c
          $(AFS_CCRULE) $<
