[Qemu-devel] [PATCH v7 09/54] tests/tcg: move architecture independent tests into subdir

["Alex Bennée" <alex.bennee@linaro.org>]

We will want to build these for all supported guest architectures so
lets move them all into one place. We also drop test_path at this
point because it needs qemu utils and glib bits which is hard to
support for cross compiling.

v2
  - move VPATH and TESTs setup into multiarch/Makefile.target
  - remove moved bits from tests/tcg/Makefile
v3
  - use LDFLAGS+= for testthread linking
v4
  - make myself MAINTAINER for tests/tcg/multiarch
v5
  - split test-mmap into run-test-mmap and run-test-mmap-%
