This makes the ARM virt machine build to fail for missing
the build_tpm2() symbol.

You probably need to split the patch in 2 and rearrange the
series:

1/ hw/i386    (current 1)
2/ hw/arm     (current 2)
3/ hw/acpi    (current 1)
4/ sysemu/tpm (current 3)

I took a bottom-up approach where I also eliminated all callers. So from 
what I can see build_tpm2() symbol has been eliminated by both i386 and 
aarch64, but ok, I will change it to a top-down approach.

I believe this is on top of Philippe's "[PATCH v2 2/2] tpm: Return QMP
error when TPM is disabled in build"

Based-on: <20210609184955.1193081-3-philmd@redhat.com>

However, it should probably go *first*, so the additional 'if' to
suppress warnings about unused qmp_marshal_output_TpmFOO() can be
squashed into Philippe's patch.

Apart from that, this looks good to me!

Additional 'if':

No, my series is stand-alone.
