Are you cross-compiling? This will not work directly, as during the
make process, a couple of programs have to be run on the same machine as
the compiler.

I don't know the sources of 2.6 (I assume they will be similar), but with
GNU Go 3.0.0 or 3.1.x the following should work (it is a little messy but
the easiest I can think of):
1. configure and compile GNU Go for the machine with which you are
   compiling
2. Now configure again, setting the compiler to the cross-compiler
3. remove all object files (rm engine/*.o patterns/*.o interface/*.o
   sgf/*.o engine/*.o utils/*.o) and interface/gnugo
4. Edit the file patterns/Makefile by removing all files *.db and
   *.sgf wherever they are mentioned
5. Similarly edit sgf/Makefile by removing sgf_properties.def and
   sgf_extras.def wherever they are mentioned
6. Now try to run make again.

I am not sure whether the above method qualifies as without hacks...
Anyone have a shorter method?
