- Allow pkg-config to use to be configured via PKG_CONFIG variable, for easier cross building (thanks Helmut Grohne in Debian bug #908525).
- Improve build system to allow cleaner separation between static and dynamic builds.
- Add a configuration option for TS-219 to allow configuring the number of fans, which removes a spurious log error message relating to fans which don't really exist (thanks to Yannis Tsopokis for the patch).
