Remove init_array / fini_array configure test.
There is a configure test "for .preinit_array/.init_array/.fini_array support". Support for this feature was added in binutils 2.13, so the configure test is obsolete; this patch removes it. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). * configure.ac (libc_cv_initfini_array): Remove configure test. * configure: Regenerated.
