The kernel passes the ArmV6K architecture to the compiler when
using the multi platform selection and enabling ARMv6. Clang
older than version 8.0 emit assembly with an non-existing CPU,
which then makes the assembler fail. Prevent the user from
selecting ARMv6 when using Clang before 8.0.

Perhaps it'd be better to avoid this in selection
criteria in Kconfig and instead add this to

(a) does it makes sense to have arch CONFIG_* in linux/*.h? It could
instead go in arch/arm/kernel/asm-offsets.c, where we have the other
tests similar to this for GCC.
(b) do we get far enough that the #error will be generated before the
reported assembler error happens? IOW, would the assembler error
mask this #error?
I think it needs confirmation that a #error for this problem results
in the desired behaviour.

Adding the above #error errors out before the assembler error happen in
both cases.
