I'm eyegrepping through xorn/configure and it seems that those macros
expand so that they call pkg-config with a syntax it can0t uderstand.
For example:

pkg-config --exists "python2 >= 2.7"

First, my pkg-config never lists python2 package. all I have is various 
python-x.y packages ( python-2.7, python-3.6 etc).

Second,my pkg-config doesn't accept "package >= version" operator.
All i can check is whether particular package version exists, e.g.
"pkg-config --exists python-2.7" works
