[Qemu-devel] [PATCH V12 1/7] Build system clean tests directory clearly

[Wenchao Xia <xiawenc@linux.vnet.ibm.com>]

  Currently root Makefile try clean tests/tcg, hard to extend.
This patch added command make check-clean, which clean all
generated files used in tests. With this command root Makefile
do not care tests clean method any more, it simply calls the
command to do it, so any more clean script could be added in
tests/Makefile, make it easier to extend.

v2:
  Discard env MAKEFILES, always include tests/Makefile.
