configure: Set LD_STAGE0 appropiately when 9.10.1 is used as a boot compiler

In 9.10.1 the "ld command" has been removed, so we fall back to using
the more precise "merge objects command" when it's available as
LD_STAGE0 is only used to set the object merging command in hadrian.

Fixes #24949

hadrian: Don't build ghci object files for ./hadrian/ghci target

There is some convoluted logic which determines whether we build ghci
object files are not. In any case, if you set `ghcDynPrograms = pure
False` then it forces them to be built.

Given we aren't ever building executables with this flavour it's fine
to leave `ghcDynPrograms` as the default and it should be a bit faster
to build less.

Also fixes #24949

hadrian: Remove STG dump from ticky_ghc flavour transformer

This adds 10-15 minutes to build time, it is a better strategy to
precisely enable dumps for the modules which show up prominently in a
ticky profile.

Given I am one of the only people regularly building ticky compilers I
think it's worthwhile to remove these.

Fixes #23635

hadrian: Add dump_stg flavour transformer

This allows you to write `--flavour=default+ticky_ghc+dump_stg` if you
really want STG for all modules.

AArch64: Simplify stmtToInstrs type

There's no need to hand `Nothing`s around... (there was no case with a
`BlockId`.)

AArch64: Simplify stmtsToInstrs type

The `BlockId` parameter (`bid`) is never used, only handed around.
Deleting it simplifies the surrounding code.

Fix eta-expansion in Prep

As #25033 showed, we were eta-expanding in a way that broke a join point,
which messed up Note [CorePrep invariants].

The fix is rather easy.  See Wrinkle (EA1) of
Note [Eta expansion of arguments in CorePrep]

ci: Unset ALEX/HAPPY variables when testing bootstrap jobs

Ticket #24826 reports a regression in 9.10.1 when building from a source
distribution. This patch is an attempt to reproduce the issue on CI by
more aggressively removing `alex` and `happy` from the environment.

hadrian: Ignore build-tool-depends fields in cabal files

hadrian does not utilise the build-tool-depends fields in cabal files
and their presence can cause issues when building source distribution
(see #24826)

Ideally Cabal would support building "full" source distributions which
would remove the need for workarounds in hadrian but for now we can
patch the build-tool-depends out of the cabal files.

Fixes #24826

testsuite: Don't attempt to link when checking whether a way is supported

It is sufficient to check that the simple test file compiles as it will
fail if there are not the relevant library files for the requested way.

If you break a way so badly that even a simple executable fails to link
(as I did for profiled dynamic way), it will just mean the tests for
that way are skipped on CI rather than displayed.

Add support for building profiled dynamic way

The main payload of this change is to hadrian.

* Default settings will produced dynamic profiled objects
* `-fexternal-interpreter` is turned on in some situations when there is
  an incompatibility between host GHC and the way attempting to be
  built.
* Very few changes actually needed to GHC

There are also necessary changes to the bootstrap plans to work with the
vendored Cabal dependency. These changes should ideally be reverted by
the next GHC release.

In hadrian support is added for building profiled dynamic libraries
(nothing too exciting to see there)

Updates hadrian to use a vendored Cabal submodule, it is important that
we replace this usage with a released version of Cabal library before
the 9.12 release.

Fixes #21594

testsuite: Make find_so regex more precise

The hash contains lowercase [a-z0-9] and crucially not _p which meant we
sometimes matched on `libHS.._p` profiled shared libraries rather than
the normal shared library.
