No clue.

I see this too (Linux/x86-64).

Expected, gdbserver doesn't support disabling randomization.

I don't see this one.

Expected.

I see this too.

I see this too.

I don't see this one.  May be a red herring -- gdbserver doesn't
support what's being tested, IIRC.

Expected, gdbserver doesn't support following exec or fork events.

Only recently (a couple of days) have the gdb.trace/ tests started
running against gdbserver (it didn't support tracepoints before),
but, none of these fails are expected on x86_64.  The all pass
for me.  I'd like to understand them.  What are the failures like?
