The main output started to retain dependency on bootstrap-tools; see
https://github.com/NixOS/nixpkgs/pull/15867#issuecomment-227949096
This reverts commit c05d8295988697adbb920a7b4a999ae3670c5504, reversing
changes made to f073df60d60444c30c49cb26d6b187a4100b41fe.
Now without some options, reflecting upstream development.
In special, no GTK building (as it was obsoleted on 096)
and no profile selecion, because it will be obsoleted
on next release.
In order to increase portability and flexibility, now the build phase
explicitly sets "compiler=c++" as a make parameter.
Further, there is a link "higan" for backwards compatibility; higan was
split in icarus (the game ROMS database manager) and tomoko (the
emulator itself).
Now we can parametrize Higan locally.
By default, guiToolkit = "gtk" and profile = "performance" (the accuracy
profile is seriously slow on my machine :) )
Closes#4340
Higan uses a lot of hardcoded paths when it looks for runtime files
as shaders, icons and mainly BIOS files. So, we made a q&d wrapper
script: it copies all these files to $HOME/.config/higan in the 1st
invocation.
Higan is a cycle-accurate Nintendo multi-system emulator
It is a preliminary release for Nix - I need to investigate
some issues about install process and hardcoded paths...
