I am not exactly fond of Eclipse, so I wanted to find a way for using the standard GNU-command line drill relying on Intel's SDK for Edison.
The process is not exactly well documented and the current version of SDK for Mac (1.7.2) is broken (it misses a shared library). So I've put up a setup guide and I am sharing it here, maybe it can prove useful for people like me on a Mac. It should work as well for linux, although I haven't check yet.
The guide is here: https://gist.github.com/pbosetti/027125c4ba066f51bf2c Intel edison cross compiling tricks on OS X · GitHub
