Still barebones and only to serve as a starting point and guideline for
how to integrate mostly non autotools environments.
Selects Intel 32-bit specifically as it is the one that has been tested
the most and also has the less number of warnings.
Test should be improved further so it is at least equivalent to what is
done in Linux, but that is orthogonal to having it integrated, and the
tests that were disabled would work locally (albeit in a newer version),
so this at least does the minimum to prevent regressions by validating
both the interpreter and JIT.

At least in OpenBSD, there is a libedit library in base, but without
public headers. Public headers for readline are available but since
15db5d36 (pcre2test: avoid using readline headers with libedit,
2022-04-07) won't be picked up automatically.
Allow pointing cmake to those headers by doing (for example):
$ cmake -DEDITLINE_INCLUDE_DIR=/usr/include/readline
Or using custom CPPFLAGS with configure (for example):
$ CPPFLAGS=-I/usr/include/readline ./configure --enable-pcre2test-libedit
Since the headers from readline.h would be otherwise incomplete, detect
that case and pull the extra headers that are required automagically and
while at it, cleanup the NCURSES dependency that was unnecessarily copied
from readline.
* pcre2test: use the right header for libedit in FreeBSD with autoconf
When `./configure --enable-pcre2test-libedit` is used in FreeBSD,
the resulting test will succeed but won't set the necessary flag
to distinguish between libedit and readline header files, therefore
using readline's at built time (if installed)
Consolidate all header tests into one and use instead the corresponding
autogenerated defines to check for each possibility.
* pcre2test: really allow libedit with cmake
Using cmake to configure and enable linking pcre2test with libedit,
could result in a broken build, because the header used was instead
pointing to readline.
In cases were the build will succeed (because both libraries were
available), it would likely show warnings, because several history
functions were being used without declarations, since readline
requires including "history.h" for those.
Additionally, since PCRE2_SUPPORT_READLINE is ON by default (unlike
configure), turning PCRE2_SUPPORT_LIBEDIT=ON, would require setting
that other option to OFF explicitly (even if readline wasn't available)
or the setup would abort.
Lastly, in systems with no default sysroot (ex: macOS), the use of
absolute paths for searching for libedit's readline.h could fail so
use instead relative PATH_SUFFIXES.
* pcre2test: avoid using readline headers with libedit
When asked to enable libedit in a system that ALSO has readline,
the headers of the former would be found and used by the earlier.
While that would mostly work, some functions will be missing
definitions (which is forbidden in C99), so instead abort the
configuration and let the user provide for them.
