So the offending code is:

syscall.c
long syscall(long sysnum,
                         long arg1, long arg2, long arg3,
                         long arg4, long arg5, long arg6)
{
register long __sc3 __asm__ ("r3") = sysnum;
register long __sc4 __asm__ ("r4") = (long) arg1;
register long __sc5 __asm__ ("r5") = (long) arg2;
register long __sc6 __asm__ ("r6") = (long) arg3;
register long __sc7 __asm__ ("r7") = (long) arg4;
register long __sc0 __asm__ ("r0") = (long) arg5;
register long __sc1 __asm__ ("r1") = (long) arg6;
__asm__ __volatile__ (
        "trapa %1"
        : "=z" (__sc0) \
        : "i" (__SH_SYSCALL_TRAP_BASE + 6),
          "0" (__sc0), "r" (__sc4), "r" (__sc5), "r" (__sc6), "r" (__sc7), \
          "r" (__sc3), "r" (__sc1) \
        : "memory" );
__syscall_return(long,__sc0);
}

and unistd.h:
extern long int syscall (long int __sysno, ...) __THROW;

The question now is how to fix this for SH.
