There should be no compatibility problems with old compiled apps.  They'll 
continue to pass _init and _fini to __uClibc_main, which will continue to 
call the functions passed.

(I'm presuming old apps don't use init_array / fini_array / preinit_array.  
If they do, none of those functions will previously have been called; 
after an upgrade of the shared uClibc, the app's preinit_array and shared 
libraries' init_array and fini_array will start getting called, but the 
app's init_array and fini_array won't get called without relinking.)
