Log message:
Remove USE_BUILDLINK3 and NO_BUILDLINK; these are no longer used.

Log message:
Add expat buildlink3.mk, since configure wants expat.

Log message:
Add weird hack to make the configure script work. The script doesn't
seem to work with pkgsrc. I don't know what's going on...

Log message:
update to 4.6.5, changes compared to 4.6.4:

Common:
- shipshape bug that could crash server or client or allow bad shapes fixed

Client:

- bug fixed in xpilotrc parsing, e.g. in 4.6.4 this xpilotrc line could not
  be parsed properly:
  xpilot.msg2:#=[#t|2|/team 4|/team 2]
- SDL client fixes: quit button works on windows, configure menu fix
- xp5 style OpenAL sound support

Server:

- constantSpeed aka oldThrust server option, which can give more agility to
  ships; especially on high fps this should allow better dodging of shots
  (polybloods.xp2 map has value 0.5 for this option)
- "shots from empty space" bug fixed by uau
- server ranking related changes: stats command can now show stats
  of players not playing (requires giving whole nick to stats command),
  logout messages in rank webpage now work even after server restart
- nuke command (to reset stats) removed, might be replaced later by some
  /setscore or such
