>Description:
Hi guys,

on a rpi2, with netbsd-7.1 stable, and the current pkgsrc, I can't build php72 because of some error during configure time. 

Here you go:

- php72 build fail if readline is enabled (as per default : --with-readline).
- php72 builds fine with readline disabled (--without-readline)

Readline (gnu package) builds fine and is installed from same pkgsrc, headers, libs are present on the filesystem.
php72's configure script detects the readline libs, but is seems the code verification fails. See enclosed config.log files.

For information: php71 build fine with readline. Providing php71 config.log file too.

php72 --with-readline config.log : https://framabin.org/?34ae0565c4d4e37d#spgUqP6Qp0cZe9q0V4lpWZu4/4cA49YVLVQ6qg78he4=
php72 --without-readline config.log : https://framabin.org/?f297d6f2661a72d5#7Sw3mUX8ZAuq5Y/8UZICptCw2UROmfH1AYz0HntjzMY=
php71 --with-readline config log : https://framabin.org/?94689bd6a4ae985f#A7C++OCuQe/XPHdtDjB9zQ6ZogIGGbODyv18UmUKL4I=


Kind regards,

>How-To-Repeat:
get pkgsrc
in php72: make
>Fix:
Workaround: disable readline in php72 config options, it does compile well.
