-`base16-builder` node package has been removed due to lack of upstream maintenance.
- The default glibc ELF ABI for the powerpc64-linux platform has been changed from ELFv2 back to ELFv1, due to the latter having less remaining issues when bootstrapping & building Nixpkgs packages on hardware.
If glibc ELFv2 is desired, use a fuller target triplet like `powerpc64-unknown-linux-gnuabielfv2` or the provided `ppc64-elfv2` platform example.
-`python3Packages.bjoern` has been removed, as the upstream is unmaintained and it depends on a 14-year-old version of http-parser with numerous vulnerabilities.
-`buildGoModule` removes the compatibility layer of `CGO_ENABLED` not specified via `env`.
