I notice he already checked in later in my inbox.  I'll reply to that there.

Well this is odd but I was poking around trying to resolve a bunch of 
syntax errors in the Makefiles.  This is usually the result of a wrong 
sh being called.  I've had some luck in the past building other things 
by adding a line "!#/usr/xpg4/bin/sh" at the top of the sh file but that 
trick did not work for qemu.  So I finally took the default sh, which is 
/usr/bin/sh (which is a link to /sbin/sh) and instead linked it directly 
to /usr/xpg4/bin/sh.  That immediately took care of all the syntax 
errors and the gcrypt error too.  I don't know why qemu is picky about 
POSIX, but there you have it.

This will probably make you cringe, but what I ended up doing was simply 
copying some random .so file in /opt/csw/lib and calling it libutil.so.  
The linker then seemed happy and that error went away. I figure that if 
someone is actually using lutil I will get a runtime error, once I get 
it running, if I ever get it running. Then I'll be able to tell who is 
calling it and what they're trying to do.  It may be that no one is 
using it.  I saw some post on the web to the effect that lutil should 
just be commented out in Solaris.  I was unable to figure out from the 
linker error the source of lutil.

I now have a new problem: dtc/checks.c won't compile because it can't 
find strnlen.  So I put in #include <string.h>.  Still wouldn't 
compile.  So I looked in /usr/include/string.h and sure enough, strnlen 
is missing.  I'm like, what the heck?  So I ended up providing the 
source code of strnlen at the top of checks.c.  This was also a problem 
in fdt_ro.c.  It's that sort of thing.  Now it's compiling again.  I 
configured without any target options, so it's making everything.  And I 
forgot to give gmake a -j so it's taking a while.
