commit 864198ed3011a446f42fc9dcb6d39617ce2477ea
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Mon Oct 19 22:34:20 2015 +0000

    Remove gnu_unique_object configure test.
    
    There is a configure test for assembler support for the
    gnu_unique_object symbol type.  This support was added in binutils
    2.20, so is present in all versions supported for building glibc.
    
    Thus, I think the configure test can be removed; this patch does so.
    Now, there is a caveat that the gas NEWS entry refers to this as a
    feature for GNU/Linux targets.  But the condition is use of
    ELFOSABI_GNU or ELFOSABI_NONE.  ELFOSABI_GNU covers Hurd as well as
    GNU/Linux (as was the case with the older ELFOSABI_LINUX name), and
    ELFOSABI_NONE means this is effectively OS-independent.  Furthermore,
    I think a correct binutils port for any glibc target ought to support
    this feature for use with glibc; glibc supports this as an
    OS-independent feature (the configure test is only about glibc
    testcases).
    
    Tested for x86_64 (testsuite, and that installed shared libraries are
    unchanged by the patch).
    
    	* configure.ac (libc_cv_asm_unique_object): Remove configure test.
    	* configure: Regenerated.
    	* config.h.in (HAVE_ASM_UNIQUE_OBJECT): Remove #undef.
    	* elf/tst-unique1.c (do_test) [HAVE_ASM_UNIQUE_OBJECT]: Make code
    	unconditional.
    	* elf/tst-unique1mod1.c [HAVE_ASM_UNIQUE_OBJECT]: Likewise.
    	* elf/tst-unique1mod2.c [HAVE_ASM_UNIQUE_OBJECT]: Likewise.
    	* elf/tst-unique2.c (do_test) [HAVE_ASM_UNIQUE_OBJECT]: Likewise.
    	(do_test) [!HAVE_ASM_UNIQUE_OBJECT]: Remove conditional code.
    	* elf/tst-unique2mod1.c [HAVE_ASM_UNIQUE_OBJECT]: Make code
    	unconditional.
    	* elf/tst-unique2mod2.c [HAVE_ASM_UNIQUE_OBJECT]: Likewise.
