    ARI: Add detection of printf_vma and sprintf_vma
    
    We shouldn't be using these, since their output goes straight to
    stdout, which doesn't allow redirection. So this patch updates
    the ARI to detect any such use.

            * contrib/ari/gdb_ari.sh: Add detection of printf_vma and
            sprintf_vma.

    Revert "bfd: allow negative offsets to _GLOBAL_OFFSET_TABLE_ in elf64 SPARC"
    
    This reverts commit b19753ce31da347605dfa903c6fd2158e2444f0d.
    
    As it turns out, GCC (and the assembler) needs additional work in
    order to support negative GOT offsets in 64-bit sparc.  This is
    breaking TLS Local Dynamic in position-independent code.
