04/08/2019: Firefox has been built

After hours of build attempts of both Chromium and Firefox, we have successfully packaged Firefox. Chromium is a story for another time. The build systems for these two browsers border on insanity and their overall size and complexity is paramount.

• Firefox requires both GTK2 and GTK3. GTK2 is required only for flash. [1]
• Both Chromium and Firefox require nodejs to build.
• Both Chromium and Firefox require Python 2.
• Both browsers bundle all of their required third-party libraries and they cannot all be set to use the system's.
• clang is now the default and "supported" compiler of both browsers.
• Firefox requires a version of automake which is 18(?) years old. [2] [3]
• Firefox requires rust which was painful to package for musl to say the least.
• Chromium's build scripts require python2 yet call python which points to python3.
• A large number of patches were needed for both to support musl.
• Both browsers depend on GTK+3 which depends on dbus. This dependency was removed by using a fake atk library.
• ALSA audio support is being removed from Firefox. This includes the configure flag to enable it.
• This will be updated as I remember things.
