- Do not depend on `dist.mak` during installPhase anymore, instead
packaging everything manually. This removes the necessity of a
patching it, and also we have more control
- Use system's sqlite instead of the bundled one
- General clean-up
This commit adds a new `tools` output to `mame` and move all
non-emulator binaries to it. This is because some of those binaries
(e.g.: chdman) are useful outside of the MAME, and the MAME binary is
really big. So if you only want to use some of the MAME tools, this will
reduce the download size needed for it.
The `tools` output is declared as `mame-tools` inside
`all-packages.nix`, for easier discovery.
This is similar to how other distros packages MAME, e.g.: on Arch Linux
we have `mame` and `mame-tools`.
