package/devel/gdb/patches/010-aarch64-headers.patch

   1 The signal definitions of musl and gdb collide
   2
   3 The kernel defines "struct sigcontext" in asm/sigcontext.h and musl libc
   4 defines it in signal.h which collides.
   5 Kernel 4.14 misses the definitions of struct user_sve_header so we still
   6 have to use the aarch64-sve-linux-sigcontext.h header file which also
   7 provides that and make sure aarch64-sve-linux-sigcontext.h does not
   8 provide the same headers as the kernel or musl.
