Log:
Merge from upstream:

commit 3e2ee6f0e3471ceb4c49f8287676a7050401bf8f
Author: Joseph Myers <joseph at codesourcery.com>
Date:   Tue Oct 27 21:46:03 2015 +0000

    Remove sysdeps/nptl/configure.ac.
    
    sysdeps/nptl/configure.ac tests for forced unwind support and the C
    cleanup attribute, giving errors if either is unsupported.  It does
    nothing beyond running those two tests.
    
    Both the attribute, and _Unwind_GetCFA which is used in the forced
    unwind test, were added in GCC 3.3.  Thus these tests are long
    obsolete, and this patch removes the configure fragment running them,
    along with associated conditionals.
    
    Tested for x86_64 and x86 (testsuite, and that installed stripped
    shared libraries are unchanged by the patch).
