[Qemu-devel] [PATCH v3 14/46] tests/tcg/multiarch: enable additional linux-test tests

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

Un-comment the remaining tests.

I removed the itimer value tests because I'm fairly sure a re-arming
timer will always have a different value in it when you grab it.

I've also fixed up the clone thread flags as QEMU will only allow a
clone to use flags which match glibc.

Signed-off-by: Alex Bennée <alex.bennee@linaro.org>

v3
  - make clone flags match CLONE_THREAD_FLAGS
