These patches add support for #pragma GCC target("...") on the powerpc to
change the default macros defined like tha x86 does (and the powerpc did for
the target attribute). When adding support for changing macros on the target
attribute, I forgot to enable the code for #pragma as well.
Also, the recip-5.c test has been failing on systems that don't support VSX,
such as Darwin. The test itself should not have been run on those system, as I
forgot to add the standard lines for VSX patches to the test. In addition,
when reporting the bug, the compiler segfaulted. This was due to the expand
builtin function returning NULL or const0_rtx (depending on the error), and the
higher level code was not expecting NULL. For this case, I did a normal
expand_call operation.
I did make boostrap and there were no regressions. Is it ok to install these
patches?

* config/rs6000/rs6000.c (altivec_expand_builtin): Call
expand_call to return a valid funciton instead of return
cosnt0_rtx/NULL_RTX if there was an error with the builtin.
(altivec_expand_ld_builtin): Ditto.
(rs6000_inner_target_options): If VSX is selected as a target
attribute or pragma, enable ALTIVEC also.
(rs6000_pragma_target_parse): Call rs6000_option_override_internal
to do all of the standard processing when switching options,
including redefining appropriate macros.

* gcc.target/powerpc/recip-5.c: Disable running on any system that
does not support VSX.
