OK, thanks.

Except for /usr/lib/libjpeg.so....

That's what I am running into....  The build fails because it insists on 
linking against /usr/lib/libjpeg.so - no matter what I do.

I'll try playing with -rpath and -rpath-link.  I have -nostdlib and 
-nodefaultlibs but they don't seem to work....  Something is explicitly 
trying to link against /usr/lib/....
