    Remove TLS configure tests.
    
    There seemed to be support in response to
    <https://sourceware.org/ml/libc-alpha/2015-10/msg00510.html> for
    removing configure tests that exist only to produce errors, where we
    expect that tool versions failing the tests would also fail the tests
    of minimum GCC / binutils versions.
    
    This patch removes the tests for TLS support as one instance of such
    tests.  Since the addition of TLS emulation support in GCC 4.3, I
    don't think these tests would have failed even if proper TLS support
    (as required by glibc) was missing in that architecture's GCC back
    end, so any new glibc ports wanting a substantive test (if there are
    actual GCC or binutils versions for those architectures, with
    supported version numbers, missing TLS support) would have needed an
    architecture-specific test anyway.
    
    Tested for x86_64 and x86 (testsuite, and that installed shared
    libraries are unchanged by the patch).
    
    	* configure.ac (libc_cv_gcc___thread): Remove configure test.
    	(libc_cv_gcc_tls_model_attr): Likewise.
    	* configure: Regenerated.
