[Qemu-devel] [RFC 05/10] tests: Support target-specific unit tests

[Eduardo Habkost <ehabkost@redhat.com>]

To make unit tests that depend on target-specific files, use
check-unit-<target>-y and test-obj-<target>-y.

Note that the qtest test cases were per-*arch* (e.g. i386, mips, ppc),
not per-*target* (e.g. i386-softmmu, x86_64-linux-user), because they
implicitly apply only to the -softmmu targets. Target-specific unit
tests, on the other hand, may apply to any target (e.g. they may test
*-softmmu and/or *-user code). To clarify this, $(TARGETS) was renamed
to $(QTEST_ARCHES).
