compile openssl on osx 10.11

libtool.pl

#!/usr/bin/perl
=pod

I have GNU libtool installed so the answer from link below not simply work:

 http://stackoverflow.com/a/30970680/3368344

The `ar` command like `ar  r ../libcrypto.a cryptlib.o mem.o ...`

This script remove `r` from arguments, and call osx libtool to merge o files to a file.

Put this file in openssl dir and run:

```
chmod +x libtool.pl
alias ar="./libtool.pl"
./Configure  darwin64-x86_64-cc
make
sudo make install
```

logs:
