So, I probably could, but if that isn't working for you, I'd quite
like to know why.

To make that a little less painful though, I've added support for
building the helloworld app to my set of scripts:
https://git.linaro.org/uefi/uefi-tools.git

This still depends on this (updated) patch.
https://lists.01.org/pipermail/edk2-devel/2016-September/002112.html

But with a current edk2, and a uefi-tools placed in the same directory
as the edk2 clone, could you try executing:

../uefi-tools/uefi-build.sh -A AARCH64 hello

If the build fails and creates messy output due to being parallel,
could you stick a -1 on that command line and send me the output (or
pastebin)?
