OK, I fixed this by adding the line

#include </usr/include/sys/ioccom.h>

to hw/tpm/tpm_ioctl.h.

gmake now went to the end but threw a bunch of errors all complaining 
about something called TFR.  This is the tail:

A web search for "solaris undefined symbol TFR" turned up nothing and 
I'm not seeing it on the machine.  man TFR returns nothing.  I didn't 
encounter this error while building 2.12.  Here's an example of its use 
(in tap-solaris.c):

  TFR(ip_fd = open("/dev/udp", O_RDWR, 0));

   What is TFR?
