[Darwin, PPC, testsuite, committed] Skip tests for unimplemented functionality.

[Iain Sandoe]

The -mno-speculate-indirect-jumps functionality is not implemented for
Darwin and, given that it's deprecated, is unlikely to be. So skip the tests
for it that fail on Darwin.

tested on powerpc-darwin9,
applied to mainline
thanks
Iain.
