Methods tried, and to be tried

Use Linux emulation to run Crystal compiler. FAILED
- OBSD Linux emulation is only for i386, Crystal binaries are 64-bit. Also OBSD i386 binaries are not compatible with amd64.

Use the first release that used a Ruby compiler to compile the next version (and so on) until we have an up to date version.
- current OBSD has llvm 3.5 in ports, the original Ruby version of Crystal targeted v3.3
- OBSD LLVM port isn't built with LLVM_ENABLE_SHARED, hopefully this is an easy change
- to simplify things it may be easier to build on a version of OBSD that supports LLVM 3.3
