[PATCH 2/8] arc: Move SYS_LITTLE_ENDIAN / SYS_BIG_ENDIAN selection to Kconfig

[Tom Rini]

We can determine which of these we need given CPU_BIG_ENDIAN being
enabled or not, so move that logic to Kconfig from config.mk.

This is not a size neutral patch as apparently before we were not fully
populating SYS_BIG_ENDIAN to all of the codebase, so testing this on
nsim_700be or nsim_hs38be would be a good idea.
