+ compiler flags will fail to build due to this -I flag

+Description: version_generator.py: make build reproducible
+ If SOURCE_DATE_EPOCH is defined then the user is most likely interested
+ in building the library in a reproducible way. So in that case use fixed
+ "BuildSystem" and "BuildMachine" strings instead of the operating system
+ and architecture.
