Description:
------------
I'm trying to build custom php binary with libffi using that script:
https://github.com/Frago9876543210/php-build-scripts/blob/master/compile.sh

However, the build failed while compiling ext-ffi.

All build logs available here:
1) Appveyor CI
https://ci.appveyor.com/project/Frago9876543210/php-build-scripts
2) install.log artifact
https://ci.appveyor.com/api/buildjobs/kjnbmmoj875p7j24/artifacts/install.log

CI script completed successfully, but it doesn't contains php binary

Are you trying to cross-compile?

@cmb No, I'm trying to build regular dynamically linked binary for x86_64

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

That build script is wrong, it configures libffi in a non-standard location and does not paass that location to --with-ffi.

The build is linking against a system libffi which is too old (missing symbols).

This has been reported before and is not a bug in ffi, it's a bug in your build.
