force symbol to local

Hi Noah,

The linker does not have this functionality but the objcopy program does.

This is slightly tricker.  The easiest way would be to use the "nm" 
program to obtain the full list of global symbols in the object file(s) 
and then use a script to extract all the ones you want to keep as 
global.  Then use the "--localize-symbols" switch supported by objcopy 
to take the remaining symbols and convert them into local symbols.

Cheers
