Ypu haven't quoted the arguments to AC_CHECK_FUNCS, so the commas in 
AC_CHECK_LIB are taken to be argument delimiters in AC_CHECK_FUNCS.  
Something like this ought to work (I haven't checked the syntax for the macro 
calls, I'm just adjusting your quoting -- although you have misunderstood how 
to call AC_REPLACE_FUNCS):

AC_CHECK_FUNCS([strrchr],
    [],
    [AC_CHECK_LIB([iberty],
        [strrchr],
        [AC_REPLACE_FUNCS([strrchr])])
    ])

Cheers,
        Gary.
