Subject: [PATCH] Fix compilation of gdb/arm-linux-nat.c on Raspbian GNU/Linux
7

GDB trunk fails to compile on Raspbian GNU/Linux 7 because
PTRACE_GETREGSET and PTRACE_SETREGSET are not defined in sys/ptrace.h.

This patch includes the gdb header file nat/linux-ptrace.h, which provides
fallback definitions.
