Thanks Roland.

That worked, but sadly seems to have just uncovered why the gcc option was removed. Built with clang my chromium still doesn't function properly. Attempting to build with gcc produces the error below.

Anyone got any idea either how to build a functioning chromium with clang, or how to successfully build it with gcc?

Attempting to build with gcc I get:
