aarch64 build fail because GHC can't be bootstraped

[nZac]

Trying to use nix-thunk:master on aarch64 is posing a number of challenges.

I got this after waiting a very long time for the compilation to finish :(

$ nix-build 
trace: Warning: `filterGit` is deprecated; switch to using `gitignoreSource`, which provides better filtering
trace: Warning: hackGet is deprecated; it has been renamed to thunkSource
trace: Warning: `thunkSet` is deprecated; use `mapSubdirectories thunkSource` instead
error: cannot bootstrap GHC on this platform
(use '--show-trace' to show detailed location information)
All done.

Any thoughts on how to get nix-thunk to work on ARM?

This should be fixed by #19. Please reopen if it isn't fixed.
