In f8ee061247, the fallback installPhase
if fFetchAttrs.installPhase is not provided, became dynamically computed.
Due to operator precedence this had the side effect of appending to
fFetchAttrs.installPhase if it is provided, breaking custom
installPhases altogether.
rustc supports way more platforms than Linux and Darwin. We might not
be able to build it for every platform at the moment, but that's what
meta.broken is for.
There are other platforms that rustc can produce binaries for, but
can't run on itself, so those are listed in the defaults for
buildRustPackage.
* buildGoModule: don't inherit postBuild hook when building go-modules
This is a slight revert of 5ce647b8bf
(#212800).
Inheriting these hooks in the `.go-modules` derivation can be confusing:
One doesn't expect them to run when generating the fixed output modules
derivation, but only on the main derivation. A `postBuild` hook that
adds some files to $out will cause a very hard to debug issue[1].
This commit adds support for a dedicated `modPostBuild` hook that will
be used only by the derivation building `.go-modules`. Additionally,
`go.section.md` now explains these attributes behavior better.

Some Flutter packages require additional attribute values to be added to buildFlutterApplication, to add things like libraries and environment variables.
To prevent duplication in applications that use the packages, a repository of package overrides is kept. buildFlutterApplication will look for package overrides for each dependency, and apply them by calling overrideAttrs on itself.
This allows thing like `flutterBuildFlags` and `runtimeDependencies` to be overridden with `overrideAttrs`.
Attributes that affect dependency retrieval cannot be overridden.
This uses `dart pub deps` (https://dart.dev/tools/pub/cmd/pub-deps) to retrieve information about project dependencies.
It requires a fetch-dart-deps derivation as input.
This wraps Flutter programs with an appropriate LD_LIBRARY_PATH.
For some reason, the RUNPATH of the executable is not used to load dynamic libraries in dart:ffi with DynamicLibrary.open().
This could alternatively be fixed with patchelf --add-needed, but this would cause all the libraries to be opened immediately,
which is not what application authors expect.
The name of the runtimeDependencies argument was chosen to match autoPatchelfHook, which has a similar feature.
This reduces the size of the executable.
It works well with Nix - if the user includes the version in their bug report, the exact debugging symbols required can easily be found.
