- Make copying to `*_names.before.txt` the responsibility of `update.sh`
(unless the file doesn't exist at all). This provides the added
benefit of allowing the inspection of the before/after state after
running a `brew update` rather than both files always being identical
at this point.
- State `No changes to formulae or casks.` on macOS.
- Rename and flip `updated_formula_report` to `auto_update`; this naming
was confusing every time.
- Only display the `You can upgrade with...` messaging if we're not
auto-updating as sometimes it will be displayed before the commands it
references (e.g. `upgrade`, `outdated` or an `install` that proceeds
to upgrade these formulae).

This wasn't working with casks because the bottle tag
would be nil here.
It was refactored to not use the bottle tag because
casks don't have bottles.
I also moved the valid_casks? method to extend/os/mac
because casks only run on macOS and the generic OS
tests were failing before.
- check the version of `/usr/bin/ld` for support of `-no_fixup_chains`
- check for usage of the `-fuse-ld` flag, since this flag is only
supported by Apple ld64
Also, call `no_fixup_chains` when setting up the build environment.
Invoking `ld` with `-undefined dynamic_lookup` emits a warning starting
Xcode 14:
ld: warning: -undefined dynamic_lookup may not work with chained fixups
Chained fixups is a linker optimisation that results in faster binary
load times, and is enabled by default starting Xcode 13 when the target
is macOS 12 or newer.
However, this interacts poorly with `-undefined dynamic_lookup`, and
Xcode will disable chained fixups when it is invoked with this flag
starting Xcode 14.3. Until then, we may be shipping binaries that are
broken in subtle ways, so let's disable chained fixups when necessary
instead.
I patterned the changes here after the handling of `-no_weak_imports`.
The only difference is that we need to check the flags that were passed
to the linker first to see if we do need to disable chained fixups.

This code is unnecessary since `--formula` is passed
by default to the install command on Linux making it
impossible to reach `Cask::Cmd::Install.install_casks`
since it is surrounded by `if casks.any?; end`.
