Serj Kalichev 8d7404149e irqbalance: Misc build enhancements
- Remove AC_CANONICAL_TARGET macro from configure to allow easier cross

- Add private implementation of called glib2 functions so that irqbalance can be
  built on systems not supporting a sufficiently recent version of glib2

- Add --without-glib2 configure option to support explicit selection of internal
  glib2 function definitions, overriding automatic selection.
