The signal definitions of musl and gdb collide
The kernel defines "struct sigcontext" in asm/sigcontext.h and musl libc
defines it in signal.h which collides.
Kernel 4.14 misses the definitions of struct user_sve_header so we still
have to use the aarch64-sve-linux-sigcontext.h header file which also
provides that and make sure aarch64-sve-linux-sigcontext.h does not
provide the same headers as the kernel or musl.

From 56893a61aa4f0270fa8d1197b9848247f90fce0d Mon Sep 17 00:00:00 2001
From: Yousong Zhou <yszhou4tech@gmail.com>

Subject: [PATCH] Fix invalid sigprocmask call
The POSIX document says
The pthread_sigmask() and sigprocmask() functions shall fail if:
[EINVAL]
The value of the how argument is not equal to one of the defined values.
and this is how musl-libc is currently doing. Fix the call to be safe
and correct

gdb/ChangeLog:
2017-03-24 Yousong Zhou <yszhou4tech@gmail.com>
* common/signals-state-save-restore.c (save_original_signals_state):
Fix invalid sigprocmask call.
