2.6.18-stable review patch. If anyone has any objections, please let us know.
------------------

From: Hirokazu Takata <takata@linux-m32r.org>

The m32r kernel 2.6.18-rc1 or after cause build errors of "unknown isa
configuration" for userspace application programs, such as glibc, gdb, etc.

This is because the recent kernel do not include linux/config.h not to expose
kernel headers for userspace.

To fix the above compile errors, this patch fixes two headers ptrace.h and
sigcontext.h for m32r and makes them platform-independent.
