Work done to build blender on Linux [sparc64].

extern/ode/dist/ode/test/test_ode.cpp:
- Don't include <ieeefp.h> on sparc linux, it doesn't exist.

extern/ode/Makefile:
- While hacking on ode, get rid of that annoying infinite rebuild

source/Makefile:
- Define a default BINTARGETS (just blenderdynamic) for linux, individual archs
  can override/add to that if they so please

source/nan_link.nmk:
- Add a sparc64 arch target to the linux section of nan_link.mk, using the same
  options as powerpc

After the first ode problem, the build completed all but the linking of a
blender binary, because there wasn't any target defined!

On the rebuilding: The usersettings would have a newer date than targets
depending on it, so it would rebuild entirely. I haven't really fixed this, but
isolated it to the platforms where usersettings need to be moved around (darwin
and windows). FBSD patches the usersettings, so it might still happen there.  I
didn't bother with a proper fix, as it looks like we're moving to scons soon.
I'm amazed no one got annoyed enough before to take care of this.
