Arity inference in type declarations was introduced
as a workaround for the lack of @k-binders.
They were added in 4aea0a72040, so I simplified all
of this by simply removing arity inference altogether.
This is part of GHC Proposal #425 "Invisible binders in type
declarations".

The previous configuration script to test whether Ld supported response
files was
* Incorrect (see #23542)
* Used, in practice, to check if the *merge objects tool* supported
response files.
This commit modifies the macro to run the merge objects tool (rather
than Ld), using a response file, and checking the result with $NM
Fixes #23542

We used to choose flags to pass to the toolchain at runtime based on the
platform running GHC, and in this commit we drop all of those runtime
linker checks
Ultimately, this represents a change in policy: We no longer adapt at
runtime to the toolchain being used, but rather make final decisions
about the toolchain used at /configure time/
(we have deleted Note [Run-time linker info] altogether!).
This works towards the goal of having all toolchain configuration logic
living in the same place, which facilities the work towards a
runtime-retargetable GHC (see #19877).
As of this commit, the runtime linker/compiler logic was moved to
autoconf, but soon it, and the rest of the existing toolchain
configuration logic, will live in the standalone ghc-toolchain program
(see !9263)
In particular, what used to be done at runtime is now as follows:
* The flags -Wl,--no-as-needed for needed shared libs are configured
into settings
* The flag -fstack-check is configured into settings
* The check for broken tables-next-to-code was outdated
* We use the configured c compiler by default as the assembler program
* We drop `asmOpts` because we already configure -Qunused-arguments flag
into settings (see !10589)
Fixes #23562
