base.bbclass: introduce COMPATIBLE_TARGET_SYS

This patch introduces COMPATIBLE_TARGET_SYS
It is similar to COMPATIBLE_MACHINE but where COMPATIBLE_MACHINE
is used to specify that a certain recipe is for a certain machine
COMPATIBLE_TARGET_SYS can be used to specify that a certain recipe
is for a certain architecture.
