Yes, it would trigger the abort.
And, that test case exposed a larger issue: config-devices.mak and
config-all-devices.mak are not added to the config-host.h and
x86_64-softmmu/config-target.h config files which means the addition of
the ifdef makes it disabled all the time -- regardless of the y/n
setting in the config*.mak file. ie., a patch is needed to get the
config*device.mak options added to the config*.h file.
