commit b9eaf28a640bdfbfbad55cdfe0361339664ab8ba
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Fri Nov 6 13:20:26 2015 +0000

    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.
