It seems firefox 56.0bN requires clang to be available. 

Now, this is not really an issue for most firefox users. But for those of us that compile our own programs using the gnu toolchain this prevents us from using your browser.

Are Mozilla deprecating the GNU toolchain? As an outsider i've failed to locate any information on this subject.

Are you enabling stylo?  clang is required to build stylo, but you don't necessarily have to use it as the C++ compiler for the browser itself.

Using --disable-stylo should be enough to not require clang.

I wasn't explicitly enabling stylo, but it was indeed enabled by default. Disabling it allows the build to continue. Thanks!
