[PATCH] microblaze: Build userprogs for the correct endianness

[Thomas Weißschuh]

Currently microblaze userprogs are built for whichever endianness is the
default for the use toolchain. They may not be the correct one for the
actually built kernel.

Implement the correct hooks to build userprogs so they can run on the
built kernel. Also test the endianness in CC_CAN_LINK.
