chrg6 755e56065a Let the lazy write-back choice check find its compiler by itself.
tests/wb_lazy_check.py took the compiler from tests/diff/common.py, which imports Unicorn and Capstone before anything else: on a PC without them the check stopped at the import, though it needs only a C compiler. It now picks the compiler as tests/gpa_check.py does.

"""Build and run tests/wb_lazy_check.c: runtime/wb_lazy_choice.h, whether the lazy write-back runs, by the player's
setting, the platform and the GPU driver.
Needs a C compiler only: no Vulkan headers, no GPU and no game files.
