[Qemu-devel] [PATCH v2] tests: Fix broken tcg test compilation

[Michal Privoznik <mprivozn@redhat.com>]

The first build error to be seen is that linux-test.c fails to
include cutils.h:

linux-test.c:42:25: fatal error: qemu/cutils.h: No such file or directory

This is because toplevel include/ dir is not put onto compiler's
command line. After that:

qemu.git/include/qemu/cutils.h:171:1: error: unknown type name ‘bool’

So we need to include "qemu/osdep.h" which will define bool type
for us. However, osdep.h eventually includes glib.h from system,
therefore we need to put GLIB_CFLAGS onto compiler's command line
too.

Lastly, getrusage is used in linux-test.c. This function and a
struct it uses are defined in sys/resource.h:

linux-test.c:247:5: warning: implicit declaration of function ‘getrusage’

diff to v1:
- Move include of osdep.h in linux-test.c at the beginning of the file as
  suggested by Eric in review
