Predefine __ppc and __ppc__ for VxWorks 7
Unfortunately, some VxWorks 7r2 system headers rely on a
couple more variations of the predefined macros expected
to characterize a "powerpc" target that we discussed recently.
setjmp.h, for example, relies on __ppc and the absence of
a definition results in "gcc" dejagnu test failures from all
the tests #including that header, which stumble on:
#error "_JBLEN not set!"
The other case is __ppc__ expected by yvals.h, key to libstdc++.
This change adjusts the VxWorks 7 section of our configuration
to honor those expectations.

* config/rs6000/vxworks.h (TARGET_OS_CPP_BUILTINS): Also
builtin_define __ppc and __ppc__ for VxWorks 7.
