Message:

add Abstract32 Little Endian architecture (abs32le)

the purpose of this special architecture is code verification and checking
(some tools cannot parse code with platform specific constructs or assembler),
it can be also used as a simple description of arch/genarch/generic kernel
interface and a starting point for new ports

(still work-in-progress: kernel compiles, but does not link due to several
missing symbols)
