Build for freedesktop-sdk 21.08beta

[abderrahim]

This needs to be merged to a branch named beta. Until such a branch is created, I'm keeping it a draft

Fixes #4

What's -Qunused-arguments? and why is it enabled only on aarch64?

beta branch has been created.

Thanks, this is now ready. I'm not sure about the -Qunused-arguments on aarch64, but it works fine on x86_64.

Seems you pushed (something equivalent to) one of the commits when creating the branch. I rebased on top of that.

What's -Qunused-arguments? and why is it enabled only on aarch64?

Se 1ea7d9a for explanation. It's needed only when build with clang. I think ideally we should make 2-stage build when 1-stage is temporary compiler build with gcc then 2-stage is full featured llvm build with compiler from stage 1.

[Erick555]

Size of extension build with gcc is 941.0 MB while current is 580.8 MB which illustrates why 2-stage build may be desirable here.

@Erick555 @Lctrs would it be possible to land this soonish? This is blocking the update of GNOME to new freedesktop-sdk base: https://gitlab.gnome.org/GNOME/gnome-build-meta/-/merge_requests/1238

[abderrahim]

I've opened #6 for the two-stage build
