Hi all,
Since around Firefox 49, I've had trouble cross compiling Firefox using
mingw-w64 and GCC. With the environment set up properly, I get an error log as
follows:

It doesn't matter if the host is Linux, macOS or MSYS2, the exact same error
happens. Firefox 45 cross compiles fine, so I'm assuming it's to do with the
new build system changes. Could anyone with a bit more knowledge on the changes
shed some light on what could possibly be happening?
