Correct test for Windows (hopefully) that makes make on Linux work again

Adds missing closing bracket to eunit instructions
Force use of GNU Make on FreeBSD

The Makefile is not compatible with BSD make, and will produce the
following error when used on FreeBSD:

  Error expanding embedded variable.
  ERROR: Command [compile] failed!

Also, os:type/0 will probably never return a generic "bsd" as the
operating system: according to os(3), the value from "uname -s" will be
used.

Transform lists:reverse(X) ++ Y to lists:reverse(X, Y)

It's 10-50% faster (typically 25-40%) and halves memory GC pressure.
It has small effect to overall performance (26.9s vs 28.7s in proper_tests)
but low hanging fruit and just bothers me.
Simplify zip/2 function.

Tail call recursion + lists:reverse/1 is no longer fastest on all
platforms.
Process parallel job results in same order.

First spawned processes should be scheduled in same order and also they
results or fails will be in same order in message queue. This code is
simpler and makes more efficient processing of results or killing in error
case.
Simplify add_exports/1 transformation.
Fix spec-checking of bitstr specifications when constant bitstrs are returned
Merge pull request #78 from pichi/master

Minor efficiency inprovements
Thank two more contributors
Perform some more lists:reverse/1 and ++ transformation
Pointless to do remote calls to the same module...
Fix the type of the {to_file, device()} option

A user reported that user_opts() type does not contain: {'to_file', 'user'}
even though this option is the suggested way to integrate PropEr with EUnit.
The problem is that the type used file:io_device() instead of io:device().

Thanks to Matyas Markovics for reporting this issue.
