To keep them in sync as much as possible -- would this here work?

No, this wont work because the _IOT__IOTBASE_* symbols are missing for
the tpm structs on GNU platform:
In file included from /usr/include/x86_64-gnu/sys/ioctl.h:26,
from ../backends/tpm/tpm_ioctl.h:17,
from ../backends/tpm/tpm_emulator.c:39:

undeclared here (not in a function)
290 | PTM_GET_CAPABILITY = _IOR('P', 0, ptm_cap),
| ^~~~
I have it compile because I added this here (above):
#ifdef __gnu_hurd__
#include <mach/x86_64/ioccom.h>
#endif
Without this header I do see these errors as well. Either way, am fine
with your suggestion in v5.
