Since the deprecation is fairly recent, we should warn by default.
Also fix the wording of the comment: stdenv.lib will be removed for the 21.11
release, not just deprecated (as it already is deprecated).
The `platform` field is pointless nesting: it's just stuff that happens
to be defined together, and that should be an implementation detail.
This instead makes `linux-kernel` and `gcc` top level fields in platform
configs. They join `rustc` there [all are optional], which was put there
and not in `platform` in anticipation of a change like this.
`linux-kernel.arch` in particular also becomes `linuxArch`, to match the
other `*Arch`es.
The next step after is this to combine the *specific* machines from
`lib.systems.platforms` with `lib.systems.examples`, keeping just the
"multiplatform" ones for defaulting.
Increase schedulingPriority of the bootstrap tools to unblock the
nixpkgs-unstable channel.
The channel is repeatedly blocked by the makeBootstrapTools job for
aarch64. The cause is lack of resources.
By increasing the priority, it should become the first job Hydra would
build, allowing the channel to advance quicker. Of course, it does mean
that while the channel advances, nothing else has been built.
This should be a temporary solution until we have more capacity for
aarch64.
By exporting it, we always make the new directories available
to subprocesses, regardless of whether the environment
variable existed before `nix-shell` was invoked.
This avoids the scenario where strictDeps is off and cross-compiled
XDG_DATA_DIRS content is brought into the environment.
While probably harmless for data like manpages and completion scripts,
this would cause issues when XDG_DATA_DIRS is used to find executables
or plugins. The Qt framework is known to behave like this and might
have run into incompatibilities.
XDG_DATA_DIRS is to /share as PATH is to /bin.
It was defined as part of the XDG basedir specification.

While it originated from the X Desktop Group, it is not limited to
the X11 ecosystem, as evidenced by its use in bash-completion.
The removal of ` && -d "$pkg/bin"` is ok, because this optimization is
already performed by `addToSearchPath`.
The dynamic loader on powerpc64 is called ld64.so.2 rather than
ld-linux.so.*, and was not matched by the existing pattern.
We reuse the dynamicLinker name from binutils to match a wider set
of platforms and to avoid specifying this information in two places.
