When compiling with --disable-tpm:

  ../vl.o: In function `main':
  /home/rjones/d/qemu/vl.c:4908: undefined reference to `tpm_cleanup'

This appears to have been introduced in commit c37cacabf228
("tpm: Move tpm_cleanup() to right place").

Since I posted this, there are more failures with --disable-tpm ...

Maybe we can define it to an empty macro (or inline function) in
the header file instead?
