V: REPL compilation fails on OpenBSD

[refacto]

V version: 25e7ceeef06a86f6fe3b056091ff4f4506034f46
OS: OpenBSD -current

What did you do?
After successfully compiling V, executing it results in:

V panic: V tool "/home/azarus/dev/v/tools/vrepl.v" could not be compiled
tools/vrepl.v:97:32: type `readline.Readline` has no field or method `read_line`
   95|                  prompt = '... '
   96|          }
   97|          mut line := readline.read_line(prompt) or {
                                               ^
   98|                  break
   99|          }
print_backtrace_skipping_top_frames is not implemented on this platform for now...

What did you expect to see?
Successful REPL execution.

What did you see instead?
Failure to compile the REPL.

Same as freeBSD 12.1.

Please try to copy vlib/readline/readline_darwin.v to vlib/readline/readline_freebsd.v and see if that will work @changrui ?

It workes for me. I'm running freebsd 11.3

That works for me on OpenBSD as well (with "openbsd" in the file name, of course).
