6809 Fix syscall glue for variadic functions

gcc6809 uses a fastcall calling convention with the first argument
in X, the second and up on the stack. However, variadic functions
get all the arguments on the stack. We therefore mangle the stack
for these functions so that they appear as fastcall to the kernel.
