Render branch: OSD compiles again, still not anywhere near working

git-svn-id: svn://dspnet.fr/mame/branches/ryan@23237 749742ba-7341-0410-aadc-df50b521781e
Render branch: More fixes, MAME tries to link now but fails because it's not building librender.a, help would be appreciated (nw)

git-svn-id: svn://dspnet.fr/mame/branches/ryan@23238 749742ba-7341-0410-aadc-df50b521781e
More makefile experimentation. Gives an error:
make: *** No rule to make target `obj/windows64/render/drawhal.o', needed by `obj/windows64/librender.a'.  Stop.

Please help.
