In particular, this contains Firefox-related and libgcrypt updates.
Other larger rebuilds would apparently need lots of time to catch up
on Hydra, due to nontrivial rebuilds in other branches than staging.
A .la file specifies linker flags to link with the library it describes. Its
"dependency_libs" field lists the libraries that this library depends upon.
This list often contains "-l" flags without corresponding "-L" flags. Many
packages in Nixpkgs deal with this in one of these ways:
- delete .la file [1]
- clear dependency_libs [2]
- add -L flags to dependency_libs [3]
- propagate dependencies [4]
Sometimes "dependency_libs" contain wrong "-L" flags pointing to the "dev"
output with headers rather than to the main output with libraries. They have to
be edited or deleted to reduce closure size [5].
Deleting .la files is often but not always safe [6]. Atomatically deleting as
many of them as possible is complex [7]. Deleting .la files that describe
shared rather than static libraries is probably safe; but clearing their
"dependency_libs" field achieves the same effect with less potential for
unintended consequences. This is the approach that may be enabled for all
Nixpkgs.

If there is a shared object or executable that's using
position-independent code, the file's mime type is
"application/x-pie-executable", so until this change its dependencies
wouldn't be patched.
This simply adds the mime type to the search loop.

Attributes `imageName` and `imageTag` are exposed if the image is
built by our Nix tools but not if the image is pulled. So, we expose
these attributes for convenience and homogeneity.
Skopeo used by our docker tools was patched to work in the build
sandbox (it used /var/tmp which is not available in the sandbox).
Since this temporary directory can now be set at build time, we remove
the patch from our docker tools.
The extraCommands was, previously, simply put in the body of the script
using nix expansion `${extraCommands}` (which looks exactly like bash
expansion!).
This causes issues like in #34779 where scripts will eventually create
invalid bash.
The solution is to use a script like `run-as-root`.

Fixes #34779
The hack of using `crossConfig` to enforce stricter handling of
dependencies is replaced with a dedicated `strictDeps` for that purpose.
(Experience has shown that my punning was a terrible idea that made more
difficult and embarrising to teach teach.)
Now that is is clear, a few packages now use `strictDeps`, to fix
various bugs:
- bintools-wrapper and cc-wrapper
Regression introduced in 736848723e.
This commit most certainly hasn't been tested with sandboxing enabled
and breaks not only pullImage but also the docker-tools NixOS VM test
because it doesn't find it's certificate path and also relies on
/var/tmp being there.
Fixing the certificate path is the easiest one because it can be done
via environment variable.
I've used overrideAttrs for changing the hardcoded path to /tmp (which
is available in sandboxed builds and even hardcoded in Nix), so that
whenever someone uses Skopeo from all-packages.nix the path is still
/var/tmp.
The reason why this is hardcoded to /var/tmp can be seen in a comment in
vendor/github.com/containers/image/storage/storage_image.go:
Do not use the system default of os.TempDir(), usually /tmp, because
with systemd it could be a tmpfs.
With sandboxed builds this isn't the case, however for using Nix without
NixOS this could turn into a problem if this indeed is the case.
So in the long term this needs to have a proper solution.
In addition to that, I cleaned up the expression a bit.
Tested by building dockerTools.examples.nixFromDockerHub and the
docker-tools NixOS VM test.
