With SKAS you simply do the normal "gdb ./vmlinux" rather than using the debug 
parameter - that was needed for TT only because of its weirdness (and it 
recently the ptrace proxy started being buggy too).

Make sure CONFIG_CMDLINE_ON_HOST is still disabled, because gdb seems unable 
to debug a program which ptraces itself.
