But how could tests see this?

The test are generic, not target-specific code, so they can not see things like NEED_CPU_H, of course.

But CONFIG_TCG seems to be defined in config-host.h, so you should be able to use that define, shouldn't you?

Yes, CONFIG_TCG is defined in config_hsot just for that reason:

tcg_arch = config_host['ARCH']
if not get_option('tcg').disabled()
  accelerators += 'CONFIG_TCG'
  config_host += { 'CONFIG_TCG': 'y' }

It's ugly, but I kept it that way when moving accelerator configuration to Meson.
