There is something wrong with the old gcc and the processor detection
code. It probably runs through the unoptimized mmx/avr code or it gets
lucky with stack alignment. In my 5.3 tests sshd worked and ssh didn't.
When I changed the stack offset by adding +8, ssh worked and sshd broke.
With the new assembly code, both work (sha) but appears that the other
assembly stubs are broken.
