    Remove /usr/ccs references on Solaris
    
    /usr/ccs/bin has been replaced by a symlink to /usr/bin since at least
    Solaris 11.3, so there's no reason to use that path any longer.
    
    This patch removes all references to it.
    
    Tested on i386-pc-solaris2.11.

            * configure.ac (md_exec_prefix): Don't set on Solaris.
            * configure: Regenerate.
    
            contrib:
            * make_sunver.pl ($elfdump): Remove ccs from path.
    
            gcc:
            * config/sol2.h (MD_EXEC_PREFIX): Remove.
    
            libstdc++-v3:
            * scripts/extract_symvers.pl: Remove ccs from elfdump path.
