4Subject: [PATCH] The signal definitions of musl and gdb collide
5
6The kernel defines "struct sigcontext" in asm/sigcontext.h and musl libc
7defines it in signal.h which collides.
8Kernel 4.14 misses the definitions of struct user_sve_header so we still
9have to use the aarch64-sve-linux-sigcontext.h header file which also
10provides that and make sure aarch64-sve-linux-sigcontext.h does not
11provide the same headers as the kernel or musl.
