Unfortunately there are some regressions in the GPU code that cause
Chromium and Google Chrome to crash, e.g.:
machine # [0709/084047.890436:ERROR:process_memory_range.cc(75)] read out of range[ 30.153484] show_signal: 20 callbacks suppressed

Hopefully this'll be fixed upstream before the final release (there are
bug reports for it) but for the meantime we have to launch the beta and
dev versions with "--use-gl=angle --use-angle=swiftshader".
* needs PKG_CONFIG_FOR_BUILD
* in the non-native case we need wayland-scanner (build) and
wayland-protocols (host) separately
* ar needs targetPrefix as well
Failing Hydra build: https://hydra.nixos.org/build/147238379
After the update of Rust to 1.53[1] this package broke because it's
heavily tied to the compiler version. Please note that we cannot upgrade
to the latest version (2.1.48) as this'd require unreleased features of
`rustc`.

For some reason having a file called `VERSION` in the package root directory
appears to be interfering with the build process:
```
Compiling Fl_cocoa.mm...
In file included from Fl_cocoa.mm:39:
In file included from ../FL/x.H:32:
In file included from ../FL/mac.H:50:
[...]
In file included from /nix/store/xhvrrnz8n6dxizgig46ijh59m7mfy261-libcxx-11.1.0-dev/include/c++/v1/cstddef:37:
../version:1:1: error: expected unqualified-id
1.4.0
^
```
By removing the file, the build succeeds.
