Bash takes an assignment of a string to an array variable:
local -a user_args
user_args="(foo bar)"
to mean appending the string to the array, not parsing the string into
an array as is the case when on the same line as the declaration:
local -a user_args="(foo bar)"
b0633406cb extracted the declaration before
the newly branched code block, causing string makeWrapperArgs being added
to the array verbatim.
Since local is function scoped, it does not matter if we move it inside
each of the branches so we fix it this way.
When modSha256 is null, disable the nix sandbox instead of using a
fixed-output derivation. This requires the nix-daemon to have
`sandbox = relaxed` set in their config to work properly.
Because the output is (hopefully) deterministic based on the inputs,
this should give a reproducible output. This is useful for development
outside of nixpkgs where re-generating the modSha256 on each mod.sum
changes is cumbersome.
Don't use this in nixpkgs! This is why null is not the default value.

Things done:
* SSE2 isn't available for the aarch64-target of GCC (the package builds
on aarch64 without those flags and works fine as well).
* Added missing darwin libraries.
* Applied a darwin-specific patch which disables i386 as target platform
(breaks at least on MacOS catalina otherwise).
We made an effort to support ghcide in Nixpkgs, but the complexity of the
problem is a bit too high, IMHO. We need to keep older versions of several
packages around in order to satisfy the build requirements, and some of those
older packages don't even build themselves (like hie-bios). We had ghcide
working at some point, but then it was broken again right away after a couple
of days. I fear that we'll run into that issue again and again with a setup of
that complexity.
Instead, I'd propose that we work with upstream to fix their build, i.e. let's
make sure that the proper ghcide build works with recent versions of its build
inputs.
