Remove configure tests for some linker -z options.
There are configure tests for the linker -z nodelete, -z nodlopen and -z initfirst options. These options were added in binutils 2.11, so the tests are obsolete; this patch removes them. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). * configure.ac (libc_cv_z_nodelete): Remove configure test. (libc_cv_z_nodlopen): Likewise. (libc_cv_z_initfirst): Likewise. * configure: Regenerated.
