These headers will be used to provide the ELF parsing code on all host
operating systems (including those that don't have an ELF header, e.g.
macOS). This will also allow removing various OS-dependent #ifdefs from
the cmELF code. Add a script that was used to automate this import.

I noticed that I wasn't getting any compiler warnings when testing my
merge requests locally. Turns out this happens because I am compiling
using Clang rather than GCC, so no warning flags are added to the build.
d06a9bdf3a enabled warnings by default
for GCC > 4.2, but Clang supports them too. This has been the case
since at least Clang 3.0 (I couldn't test any older versions on
godbolt.org). For AppleClang, we can also assume that the warning flags
are supported. According to Wikipedia Clang became the default
compiler starting with Xcode 4.2, and the table on
https://trac.macports.org/wiki/XcodeVersionInfo, states that XCode
4.2 Clang was based on upstream Clang 3.0, which supports all the
warning flags.
The warning flags are currently not added when compiling with clang-cl
since this exposes some pre-existing warnings that need to be fixed first.

Merge-request: !4766
In 5e941a545b (ExternalProject: Ensure git fetch if updating to hash we
don't have yet, 2021-05-09), the form ${ref}^{commit} was used to ensure
the ref was treated as a commit. When running under a MSYS2 or
Cygwin shell, the {commit} part can be translated by the shell, leaving it as
${ref}^commit, which git doesn't understand. Use the equivalent but
safer form ${ref}^0, since it won't be subject to the shell substitution
issue.
Fixes: #22299
Running `xcode -version` on an ARM box prints content to stderr:
objc[...]: Class ... is implemented in both...
One of the two will be used. Which one is undefined.
Capture and parse only stdout. Otherwise we might configure test
behavior for the wrong version of Xcode.
Extend the change from commit 9e5bbb69ea (Tutorial: Add captions for
code blocks, 2021-06-11) to also add a Sphinx named target to code
blocks. Name each target after the change the code block makes.
