There is no point in modifying MSR_LE bit on CPUs not supporting

Isn't that an ABI break?
Or an ABI fix ? I don't know.
My first thought was that all other 32 bits architectures were returning -EINVAL, but looking at the
man page of prctl, it is explicit that this is powerpc only.
set_endian(PR_ENDIAN_BIG) should work on a big endian CPU, even if it
does nothing useful.
Fair enough. But shouldn't in that case get_endian() return PR_ENDIAN_BIG
instead of returning EINVAL ?
We can do one or the other, but I think it should at least be consistant
between them, shouldn't it ?
