Done with the help of https://github.com/Mindavi/nixpkgs-mark-broken
Tool is still WIP but this is one of the first results.
I manually audited the results and removed some results that were not valid.
Note that some of these packages maybe should have more constrained platforms set
instead of broken set, but I think not being perfectly correct is better than
just keep trying to build all these things and never succeeding.
Some observations:
- Some darwin builds require XCode tools
- aarch64-linux builds sometimes suffer from using gcc9
- gcc9 is getting older and misses some new libraries/features
- Sometimes tools try to do system detection or expect some explicit settings for
platforms that are not x86_64-linux
musl and darwin support UTF-8 locales without any extras. As a result
unzip can unpack UTF-8 filenames there as is. But on glibc without
locale archive presence files get mangled as:
deps/αβ -> deps/#U03b1#U03b2
This makes `fetchzip` fixed-output derivations unstable.
Tested this change to fail in `coq.src` which was generated in system
that mangles UTF-8 symbols:

Note: it means that some of existing caches for fixed output
derivations become incorrect. It should not break already cached
tarballs on cache.nixos.org thus the impact should not be widespread.
