Use a well-known error string for out-of-bound function arguments

* src/function.c (parse_numeric): Check for empty value and error.
If we find ERANGE just print our own error, not strerror.
(func_word): Use a generic "not good" error message.
(func_wordlist): Ditto
(func_intcmp): Ditto
* tests/run_make_tests.pl: Remove code to find strerror(ERANGE)
* tests/scrips/functions/intcmp: Update the error message.
* tests/scrips/functions/word: Ditto.
