[ This shows up as the __mulkc3 etc. functions not existing at all ].

[PATCH, rs6000] Fix {div,mul}kc3-1.c for older hardware

[Bill Schmidt]

Hi,

For the subject tests, I neglected to ensure they would be skipped on
older hardware.  This patch fixes that.  Tested on
powerpc64-unknown-linux-gnu on POWER7 to verify the tests are
unsupported there, and on powerpc64le-unknown-linux-gnu on POWER8
to verify they still run there.  Ok for trunk and gcc-6-branch?

Thanks,
Bill

* gcc.target/powerpc/divkc3-1.c: Require p8vector support.
* gcc.target/powerpc/mulkc3-1.c: Likewise.
