Hi

this patch aims to add the initial arch-specific arm64 support to
kselftest starting with signals-related test-cases.
A common internal test-case layout is proposed which then it is
anyway wired-up to the toplevel kselftest Makefile, so that it
should be possible at the end to run it on an arm64 target in the
usual way with KSFT.

~/linux# make TARGETS=arm64 kselftest

Notes:
-----
- further details in the included READMEs

- more tests still to be written (current strategy is going through the related
  Kernel signal-handling code and write a test for each possible and sensible code-path)

- a bit of overlap around KSFT arm64/ Makefiles is expected with this recently
  proposed patch-series:

Looks like a good initial set of dests overall.  There are various
details that need attention, but once those are sorted out I think this
will be a decent base to build more tests on in the future.

See comments on the individual patches.
