missing instructions for setting up a cross linker for macOS #65

Closed ashleygwilliams closed 7 years ago

ashleygwilliams commented 7 years ago

add these instructions to the README: http://intermezzos.github.io/book/appendix/osx-install.html

make cargo on macOS gives this error. this is because macOS has the wrong ld (BSD), we need the GNU ld.

error: linking with `cc` failed: exit code: 1
