    classes, conf, lib: Add support for powerpc64le
    
    LE is default for modern powerpc64, power8+
    
    PowerPC64 Little Endian Linux ABI specifies Power8 as the minimum ISA.
    The basic ABI can run on earlier versions of the 64 bit PowerPC ISA,
    but it was helpful to define a new, minimum instruction set for Linux
    distribution releases during the switch to Little Endian.
