Kbuild now supports the 'userprogs' syntax to describe the build rules
of userspace programs for the target architecture (i.e. the same
architecture as the kernel).

Add the entry to samples/Makefile to put this into the build bot
coverage.

I also added the CONFIG option guarded by 'depends on CC_CAN_LINK'
because $(CC) may not necessarily provide libc.
