Extend contrib buildsystem to allow for a finer control on system and Linux distributions rules. The bootstrap tries to guess the operating system to build for by looking at the compiler prefix. For native building (usually Linux/Unix-like systems) additional matching logic should be written. Currently only Fedora-Core systems are detected as being different from the normal Unix-rules. Extend this logic to make a distinction for your system if it deviates from the standard Unix-like system that our contrib recognizes atm.
