Add Kernel Concurrency Sanitiser support for PPC64. Doing so involves
exclusion of a number of compilation units from instrumentation, as was
done with KASAN.

KCSAN uses watchpoints on memory accesses to enforce the semantics of
the Linux kernel memory model, notifying the user of observed data races
which have not been declared to be intended in source through the
data_race() macro, in order to remove false positives.

[...]

Applied to powerpc/next.
