This is GNU make specific syntax (not portable) and so you should consult the GNU make manual.
As a quick check you can add something this at the bottom of the Makefile to see what these variables end up being defined to:
test_vars: echo $(python_version_full) echo $(python_version_major) and then do make test_vars to see what gets printed.
