Not without making _start look like a proper ppc64 function
descriptor, ie. defined in .opd. But then the test would pass, and
you want it to fail on 2.16.1 otherwise you'll get the hang later when
building libstdc++. Ideally configure ought to be able to test for
a hang in ld. If that's too hard, then I suppose you could fail this
test for powerpc64 based on ld version.
