dh-php throws PHP_DEFAULT_VERSION cannot be empty

[Hans Rakers]

While trying to compile php-mongodb-1.15.1, the dpkg-buildpackage stage keeps failing with:

#12 1.337 dpkg-buildpackage: info: host architecture amd64
#12 2.192 fakeroot debian/rules clean
#12 2.966 PHP_DEFAULT_VERSION_DEFAULT := "8.1.2-1ubuntu2"
#12 2.992 PHP_DEFAULT_VERSION_OVERRIDE := ""
#12 2.992 AVAILABLE_PHP_VERSIONS := "8.1"
#12 2.992 /usr/share/dh-php/pkg-pecl.mk:39: *** PHP_DEFAULT_VERSION cannot be empty. Stop.
#12 2.997 dpkg-buildpackage: error: fakeroot debian/rules clean subprocess returned exit status 2

This appears to be related to the changes made in dh-php 4.9. These changes might work fine on Debian, but since the output of `php-config --version` is quite different between Debian and Ubuntu, the matching seems to fail in pkg-pecl.mk.

Debian:

# php-config --version | sed -E -e 's,\.[^.]*$$,,'
7.4
# /usr/sbin/phpquery -V
7.4

Ubuntu:

# php-config --version | sed -E -e 's,\.[^.]*$$,,'
8.1.2-1ubuntu2
# /usr/sbin/phpquery -V
8.1

Environment:

Ubuntu 22.04
dh-php 4.9

I run this bug too. The sed regex is wrong:

If you install main release php8.1-dev package:
# dpkg -l|grep php8.1-dev
ii php8.1-dev 8.1.2-1ubuntu2 amd64 Files for PHP8.1 module development
It works good:
# php-config --version
8.1.2
# php-config --version | sed -e 's,\.[^.]*$,,'
8.1

If you install the security package:
# dpkg -l|grep php8.1-dev
ii php8.1-dev 8.1.2-1ubuntu2.11 amd64 Files for PHP8.1 module development
It's not good:
# php-config --version
8.1.2-1ubuntu2.11
# php-config --version | sed -e 's,\.[^.]*$,,'
8.1.2-1ubuntu2

The security "long" version is the good:

Status changed to 'Confirmed' because the bug affects multiple users.
