    Revert "configure: Remove test for strlcat"
    
    This reverts commit e4e469a0ede6974e1f916843f9317244516f7674.
    
    It looks like we get to choose between breaking the clang build or the
    gcc build. With gcc, we need to ensure that enter xorg/os.h with the
    right set of HAVE_STRNDUP et al guards, e.g.
    
    In file included from /usr/include/string.h:630:0,
                     from /usr/include/xorg/os.h:53,
                     from /usr/include/xorg/misc.h:116,
                     from fd.c:34:
    /usr/include/xorg/os.h:590:1: error: expected identifier or '(' before '__extension__'
     strndup(const char *str, size_t n);
