I ran into the following failures when running tests under QEMU:

The following patch fixes those by adding the necessary include files.

With that said, the test doesn't pass at present. I'll have to investigate it
a bit more.

I get a little concerned when we have to include multiple sys, asm, bits etc
version of a header. However, saying that we include both of these in many
aarch64 gdb files (eg aarch64-linux-hw-point.c).

Ok to push.

I was expecting sys/ptrace.h to include asm/ptrace.h or something a bit 
cleaner. But it seems to be the way things are laid out at the moment, 
as some other files are doing the same.
