Take off "link" and "unlk" of function


I found m68k-coff-gcc add 'link %a6, #n' in the begin and
'unlk %a6' in the end of every function.
I knew this is because gcc try to allocate stack
for the locale variable.
But when the function is without local variable or only
content inline assmebly. It (link %a6, #0) still there.
How can I take it off.
