Linker failure outputs look like they are related to the GClosure stuff,
so lets try disabling that flag on arm — originally the upstream cabal
file disabled that flag by default if arch != x86_64-linux || != sparc64,
so this seems to be actually correct.
Test suite doesn't build with GHC 9.0.1 and since upstream is
currently not invested in fixing it, we (temporarily) disable it.
Upside: we can build hoogle again.

GHC 9.0.x seems to require that the `Main` module also defines the
`main` IO action and does not just import it. This is the case with
mono-traversable's test suite which is why we (temporarily) disable it.
Stackage Nighly recently upgraded their version of hackage-db from 2.1.0
to 2.1.1. 2.1.1 had a compatibility fix for Cabal 3.4 [1]. However it
did not increase the version bound on Cabal nor fails to compile with
Cabal 3.2, so Stackage was able to update it.
Unfortunately hackage-db with Cabal 3.2 causes observable issues [2]
in cabal2nix, so we need to downgrade it for all compilers that still
ship a Cabal version < 3.4.
Also ideally we should update the constraints for hackage-db 2.1.0 and
hackage-db 2.1.1 on hackage. See also [3].

These attribute names were converted into aliases in the following
changes:
* 62733b37b4
* https://github.com/NixOS/nixpkgs/pull/104776
cabal2nix-unstable has been updated to be aware of these changes in
7a9080d774, so these aliases should no
longer cause issues when evaluating with `allowAliases = false`.
Every flag the generic builder receives via `testFlags` is passed via
`--test-option` [1] to `Setup.hs` which in turn passes them to the
underlying test suite binary. These wrapped options are added to
`checkFlagsArray` in `checkPhase`. This needs to be done in bash since
without structuredAttrs in nixpkgs so far, Nix arrays aren't properly
translated into bash arrays, so we'd have all sorts of quoting issues
when spaces are involved.
Re-using `checkFlags` and `checkFlagsArray` from standard stdenv
setup.sh also results in an additional feature: Using `overrideAttrs`
`checkFlags` and `checkFlagsArray` can additionally be overridden,
which allows passing extra flags to `Setup.hs` whithout being wrapped
with `--test-option`.

According to the cabal-install man page this also allows passing
special variables which are substituted for other values
depending on context.
While diagrams-lib 1.4.4 doesn't per se require us to update any
diagrams lib to 1.5.0 it would require monoid-extras 0.6 which would
force us to update diagrams-core to 1.5.0, thus breaking
haskellPackages.diagrams.
Since we can just keep the patch we fetch and downgrade to 1.4.3, we
can continue sitting out the slow update cycle of the diagrams universe.
This reverts commit 52d69816b0.
Unfortunately there is no way to update to monoid-extras 0.6 yet without
marking some packages as broken. The issue is that not all diagrams*
packages have had an update adding support for GHC 9.x yet (which would
also include monoid-extras 0.6 support). The only alternative to pinning
diagrams* and monoid-extras would be to have mismatched versions between
them which always causes issues with haskellPackages.diagrams.
Note that this commit re-introduces some build failures which are to be
fixed in a follow-up commit.
