tpm2: fix build on x32

[bluca]

openssl defines SIXTY_FOUR_BIT for this architecture

./tpm2/crypto/openssl/tpm_radix.h:74:4: error: #error Need to determine RADIX_BITS value
   74 | #  error Need to determine RADIX_BITS value

Thanks. I don't have access to a machine with x32, so I trust that you tested it on such a machine.

Yes it builds and unit tests pass with this change:

Thanks. It looks like sparc64 and m68k have related problems. I probably can get rid of the sizeof() checks on OBJECT now, which may resolve the issue for sparc64 -- I will make it a TODO item.

This commit here should resolve the issue: 2672049

For m68k there's unfortunately more to it due to some checks in BackwardsCompatibilityObject.c that I had worked on in the past -- there are patches that I don't want to apply: https://github.com/stefanberger/libtpms/tree/stefanberger/force_m68k_alignment

Maybe sparc64 has the same issues. But I don't know or can read anything about it. On m68k the issue is explained here: https://wiki.debian.org/M68k/Alignment

[stefanberger]

I did merge the m68k support now as well... hopefully v0.11 will then build on it as well. It builds for me now.

FYI, @glaubitz

That's great news, thank you!
