[OE-core] [master][morty][PATCH v2] libunwind: add ptest support

[Jagadeesh Krishnanjanappa]

The patch include below changes:

1. Add do_compile_ptest task, which compiles and runs builtin
   test cases. The libunwind test scripts has relink commands,
   which needs to be run at host in order to create ELF test
   binaries which can be readily executed at target.
   Hence pass "-i" option to make, to ignore exit status of tests
   executed at host.

2. run-check-namespace test require libunwind library containing
   debug symbols to pass. Hence made ${PN}-ptest to
   RDEPENDS on ${PN}-dbg package, and added "debug-deps" in to
   INSANE_SKIP to avoid packaging error; due to dependency on
   ${PN}-dbg package.

3. Add do_install_ptest task, which copies necessary
   filesb to execute tests.

4. Add run-ptest script to execute tests at target.

5. Add dependent packages neede to execute test cases via RDEPENDS
   (run-check-namespace test requires "nm" tool, which is given by binutils)

6. Made run-coredump-unwind and run-coredump-unwind-mdi testcases as
   expected failures, due to unavailability of unstripped crasher binary.

+Testcases run-coredump-unwind and run-coredump-unwind-mdi require unstripped
+crasher binary to get procedure names via libunwind APIs. But in libunwind 
+recipe of OE-core, we remove debug symbols from crasher binary, this 
+results in failure of run-coredump-unwind and run-coredump-unwind-mdi tests.
+Hence, mark them as expected failures (XFAIL).
