MPlayer is designed around a more or less "generic" C code which  
should be relatively easy to adapt to any posix-like operating  
system, plus a variable amount of architecture dependent optimized  
code. Currently the architecture dependent code is for x86, PowerPC  
and ARM. Depending on the toolchain you're using, the generic code  
can be relatively easy to adapt, but the performance may range from  
fair to completely unusable. You should start modifying "configure"  
around the part which goes:

----%<------------
else # if test -z "$_target"
   system_name=`echo $_target | cut -d '-' -f 2`
   case "`echo $system_name | tr A-Z a-z`" in
-----%<-----------

and add your architecture, and eventually the extras needed by the  
toolchain.
