Build Qt5.9.6 fails on debian Stretch

[peke]

On both 32/64 bits versions of Debian 9.4 I've failed to successfully run configure using the following parameters:
-prefix /usr/local/qt5 -nomake tests -nomake examples -debug -opensource -confirm-license

The Error I get is "ERROR: The OpenGL functionality tests failed!"
When looking at the flags "Desktop OpenGL" and "OpenGL ES X.X", all are saying "no".

The 64 bits Debian was a clean install, only installing:
sudo apt-get install build-essential libgl1-mesa-dev
as described in:
http://doc-snapshots.qt.io/qt5-5.9/linux.html

When running configure with the same options using Qt5.9.5 (or any other previous Qt5.9.X) it passes saying I do have Desktop OpenGL.
This looks like a bug to me. Anyone?

@peke You can call configure with -v parameter - it will give you more information what exactly is missing when it tries to determine the OpenGL functionality. You can post the related parts of the output here.

In threw away the shadow build dir and it's working on my 64 bit.
Desktop Open GL says it's available.
Maybe I ran configure before installing the libgl1-mesa-dev package on my 64 bit, though it was already installed for sure on the 32 bit as I had build Qt5.9.5 on it before. Or did something change in dependencies between 595 and 596.
