Actually the reason the options are added to the end is that if you use 
something like <linkflags>-lsome_static_lib, things won't link if  
-lsome_static_lib is added to front of command line, and some libraries later 
on the command line use symbols from some_static_lib. 

Unless somebody has bright ideas, I think the only solution is to have 
OPTIONS_BEFORE and OPTIONS_AFTER variables, and convert <linkflags> to 
OPTIONS_BEFORE, which will be added to the front of command line.
