please file a bug and include a list of all the little failures and we'll get 
to it ... ive done some quick little tests on my amd64 so i should be able to 
easily test

there was brief mention of it but i never saw any code ... so i got bored and 
started it :)  i committed all my work thus far to svn before i left for LWE; 
here's a quick status report:
- crt0.S is not complete, it needs to be touched up so all the registers are 
in the correct place before jumping to uclibc main ... (look for the 
START/END TODO comments)
- syscall.S / vfork.S need to have the syscall_error handler implemented
- crti.S needs to be reviewed
- no shared library code yet since static needs to be verified first :)
