 looking into the header path issue for 32bit.

 That's on Windows 10, right? I tested the artifact
 (https://queue.taskcluster.net/v1/task/X5K6N8O8SMqb9RarbIrp2w/runs/0/artifacts/public/build/target.zip)
 on Windows 7 and it seems to crash early on. I have not looked closer why
 but I noticed that firefox.exe etc. is still linked against msvcrt.dll
 which is not working for Windows 7. So, we need to teach the toolchain
 again how to link against a non-default runtime lib (ucrt this time) which
 has always been a fun exercise...
