[M68K/ColdFire patch 4/n] Remove kernel headers

[Maxim Kuvyrkov <maxim at codesourcery dot com>]

This patch removes 2 kernel headers -- sigcontext.h and ucontext.h -- 
from GLIBC's m68k port.  These headers are installed by the kernel, that 
has a better idea of how it lays out the signal context.

This elegant patch is a result of about a day of debugging unwinding of 
the signal frames.

Any comments?

Thanks,

Subject: [PATCH 4/5] Remove kernel headers.

	* sysdeps/unix/sysv/linux/m68k/bits/sigcontext.h: Remove, use
	kernel version instead.
	* sysdeps/unix/sysv/linux/m68k/sys/ucontext.h: Same.
