multilib: Add support for compiling recipes against multiple ABIs

This patch adds the core multilib class which can be used along with a
parameter specifying the mutlilib to use in BBCLASSEXTEND.

The MLPREFIX variable is added and can be used in cases where its too
difficult to dynmaically work out where a mutltilib prefix is needed
to be added to a variable.

This includes:
  * SHLIBSDIR and PACKAGE_ARCH fixes from Lianhao Lu.
  * PACKAGE_DYNAMIC mapping from Yu Ke
  * PACKAGE_INSTALL mapping from Yu Ke
  * RPROVIDES mapping from Yu Ke
  * TARGET_VENDOR fix from Mark Hatle
  * Ignorning *-native-runtime dependnecies as well as *-native from Yu Ke
  * Map PKG and ALLOW_EMPTY from Dongxiao Xu
  * Ensure RCONFLICTS and PKG field dependencies are remapped (from Dongxiao Xu)
  * Ensure PN and MLPREFIX are set at the same time to ensure consistent BPN values (Yu Ke)
