Randy MacLeod 997d91f608 valgrind: ptest improvements to run-ptest and more
Make some changes to the run-ptest script:
  - after main tests run integrity check like the pkg Makefile.
  - aesthetic and ordering changes

Add the .in_place directory and its contents which allows valgrind
to be run in-place thereby enabling the gdbserver_tests to
complete rather than hang. Unfortunately directory paths embedded
in binaries still cause many of these test to fail.

Add the exp-sgcheck tests.

With core-image-minimal on qemux86-64/kvm:
Recipe         | Passed      | Failed   | Skipped   | Time(s)
before         | 648         | 12       | 60        | 1541
after          | 662         | 20       | 38        | 1429
ppc-no-gdbserv | 415         | 196      | 34        | 10689

Since fewer tests timeout, the overall time has decreased.
With core-image-sato on qemux86-64/kvm the results are now
the same as core-image-minimal.

qemuppc/arm64 runs result in the oom-killer eventually running since
some processes do not terminate properly and accumulate as defunct
processes in memory. Without the gdbserver_tests, the tests
complete without defunct process or the oom-killer running for
ppc but not for arm64.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
