[PATCH] switch m68knommu to using asm-generic/siginfo.h

This modifies the m68knommu siginfo include file to use
asm-generic/siginfo.h instead of the asm-m68k/siginfo.h.

The asm-generic/siginfo.h is more appropriate here, and
the m68k is out of date.

include/asm-m68knommu/siginfo.h

+#define _M68KNOMMU_SIGINFO_H

+#include <asm-generic/siginfo.h>
