[PATCH 2/2] kbuild: userprogs: also inherit byte order and ABI from kernel

["Thomas Weißschuh" <thomas.weissschuh@linutronix.de>]

Make sure the byte order and ABI of the userprogs matches the one of the
kernel, similar to how the bit size is handled.
Otherwise the userprogs may not be executable.
This happens for example on powerpc little endian, or riscv32.
