>Description:
The attached patch adds FreeBSD support to bin/expr/t_expr.sh. I had to do some 
minor refactoring to support the fact that expr on FreeBSD...
- Does option parsing
- Has different error messages when dealing with integer overflows
- Always fails with syntax errors when dealing with dangling arithmetic 
operators (and thus I had to split off the arithmetic_ops testcase into 6 
separate testcases in order to properly use atf_expect_fail).

The results can be found below for FreeBSD 11-CURRENT:
