From looking at the prerequisites at
http://webassembly.org/getting-start...elopers-guide/, I reckon most Linux distros will suffice and that the requirement to run WebAssembly shouldn't affect your choice of distro.
gcc and python are usually provided out-of-the-box, while git and cmake are usually in the repos (or, if not, you can get them from somewhere). Just to confirm that all tools are available on my Mint 18.1 box and should also be for other distros in the Debian/Ubuntu family, but it would shock me if they weren't also available in Red Hat and other families.
