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)
