Hi,

This patchset is hopefully my final attempt to upstream qemu support for GNU/Hurd.
All review comments have been considered and addressed in the patches.
Some people want minimal diff to tpm header, others want me to delete code.
I went with the reduced diff because it's only one line of code change to fix it,
and passed review originally in other attempts.

This has been rebased onto:
* cd5a79dc98 (origin/master, origin/HEAD) Merge tag 'for_upstream' of ... 

TESTED: Compiles on GNU/Hurd using:
	../configure --target-list=i386-softmmu,x86_64-softmmu
	ninja

Executed qemu-system-{i386,x86_64} on GNU/Hurd x86_64 successfully.

Thanks,
Damien
