meson, NEED_CPU_H, CONFIG_TCG and tests/

[Claudio Fontana]

Hi Paolo,

currently we have use of CONFIG_TCG in tests/,

but is that variable available at all in there?

I have to adapt some qemu/tests/qtest/* to work also without tcg for ARM,

but I think I am not seeing CONFIG_TCG filtering through, and I wonder whether 
all the checks in there are actually "wrong".

Looking at meson.build it would seem to me that only stuff in target/ would be 
able to see CONFIG_TCG,
as a result of

foreach target : target_dirs
  config_target = config_target_mak[target]
  target_name = config_target['TARGET_NAME']
  arch = config_target['TARGET_BASE_ARCH']
  arch_srcs = [config_target_h[target]]
  arch_deps = []
  c_args = ['-DNEED_CPU_H',
            '-DCONFIG_TARGET="@0@-config-target.h"'.format(target),
            '-DCONFIG_DEVICES="@0@-config-devices.h"'.format(target)]

But how could tests see this?

Thanks,

Claudio
