Makefile creates unnecessarily large programs

[GoogleCodeExporter]

When using http://www.arduino.cc/en/uploads/Hacking/Makefile instead of the 
IDE, the resulting programs are significantly larger.

Examination of the .elf file suggests that this is because unused code isn't 
being eliminated, and that the -ffunction-sections and -fdata-sections 
arguments used by the IDE should be used for compiling, and -Wl,--gc-sections 
for linking. 

The IDE also compiles with -fno-exceptions which should probably be used as 
well.

That Makefile is unsupported, so no plans to fix this.

Ok, will you accept a patch for it, then?

It's the first hit for "Arduino makefile" in google, seems sort of silly to 
have every programmer figure out how to make it work properly.

I just deleted that file, so I'm hoping Google will update their search results 
and point people to Makefiles that are actually being maintained (by other 
people).
