Fixes #24167
XCode 15 introduced a new linker which warns on duplicate libraries being
linked. To disable this warning, we pass -Wl,-no_warn_duplicate_libraries as
suggested by Brad King in CMake issue #25297.
This flag isn't necessarily available to other linkers on darwin, so we must
only configure it into the CC linker arguments if valid.

A regression in the new iconv() distributed with XCode 15 and MacOS
Sonoma causes the test 'encoding004' to fail in the CP936 roundrip.
We mark this test as fragile until this is fixed upstream (rather than
broken, since previous versions of iconv pass the test)

MacOS seems to have fixed an issue where it used to ignore the variable

In XCode 15's linker, -single_module is the default and otherwise
passing it as a flag results in a warning being raised:
ld: warning: -single_module is obsolete
This patch fixes this warning by, at configure time, determining whether
the linker supports -single_module (which is likely false for all
non-darwin linkers, and true for darwin linkers in previous versions of
macOS), and using that information at runtime to decide to pass or not
the flag in the invocation.
Fixes #24168

The recent toolchain upgrade on darwin machines resulted in the
MultiLayerModulesTH_Make test metrics varying too much from the
baseline, ultimately blocking the CI pipelines.
This commit skips the test on darwin to temporarily avoid failures due
to the environment change in the runners. However, the metrics
divergence is being investigated still (tracked in #24177)

This commit fixes an issue with ModUnusable introduced in df0f148feae.
In mkUnusableModuleNameProvidersMap we traverse the list of unusable
units and generate ModUnusable origin for all the modules they contain:
exposed modules, hidden modules, and also re-exported modules. To do
this we have a two-level map:
ModuleName -> Unit:ModuleName (aka Module) -> ModuleOrigin
So for each module name "M" in broken unit "u" we have:
"M" -> u:M -> ModUnusable reason
However in the case of module reexports we were using the *target*
module as a key. E.g. if "u:M" is a reexport for "X" from unit "o":
"M" -> o:X -> ModUnusable reason
Case 1: suppose a reexport without module renaming (u:M -> o:M) from
unusable unit u:
"M" -> o:M -> ModUnusable reason
Here it's claiming that the import of M is unusable because a reexport
from u is unusable. But if unit o isn't unusable we could also have in
the map:
"M" -> o:M -> ModOrigin ...
Issue: the Semigroup instance of ModuleOrigin doesn't handle the case
(ModUnusable <> ModOrigin)
Case 2: similarly we could have 2 unusable units reexporting the same module
without renaming, say (u:M -> o:M) and (v:M -> o:M) with u and v
unusable. It gives:
"M" -> o:M -> ModUnusable ... (for u)
"M" -> o:M -> ModUnusable ... (for v)
Issue: the Semigroup instance of ModuleOrigin doesn't handle the case
(ModUnusable <> ModUnusable).
This led to #21097, #16996, #11050.
To fix this, in this commit we make ModUnusable track whether the module
used as key is a reexport or not (for better error messages) and we use
the re-export module as key. E.g. if "u:M" is a reexport for "o:X" and u
is unusable, we now record:
"M" -> u:M -> ModUnusable reason reexported=True
So now, we have two cases for a reexport u:M -> o:X:
- u unusable: "M" -> u:M -> ModUnusable ... reexported=True
- u usable: "M" -> o:X -> ModOrigin ... reexportedFrom=u:M
The second case is indexed with o:X because in this case the Semigroup
instance of ModOrigin is used to combine valid expositions of a module
(directly or via reexports).
Note that module lookup functions select usable modules first (those who
have a ModOrigin value), so it doesn't matter if we add new ModUnusable
entries in the map like this:
"M" -> {
u:M -> ModUnusable ... reexported=True
o:M -> ModOrigin ...
}
The ModOrigin one will be used. Only if there is no ModOrigin or
ModHidden entry will the ModUnusable error be printed. See T21097 for an
example printing several reasons why an import is unusable.

A `.target` file generated by ghc-toolchain or by configure can become
invalid if the target representation (`Toolchain.Target`) is changed
while the files are not re-generated by calling `./configure` or
`ghc-toolchain` again. There is also the issue of hadrian caching the
dependencies on `.target` files, which makes parsing fail when reading
reading the cached value if the representation has been updated.
This patch provides a better error message in both situations, moving
away from a terrible `Prelude.read: no parse` error that you would get
otherwise.

In Parser.y, the tup_tail rule had the following option
| {- empty -} %shift { return [Left noAnn] }
Once this works through PostProcess.hs, it means we add an extra
Missing constructor if the last item was a comma.
Change the annotation type to a Bool to indicate this, and use the
EpAnn Anchor for the print location for the others.
