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.
