Tracking bug to fix the GDB tests on mips64.

I'm going to skip them for now.

They fail with:

Like TestLinuxSendfile, this one also passes on a 64bit rootfs. We've setup mips64be Debian Wheezy RFS yesterday for the mips64be buildbot, but it hasn't run since then.

I forgot these.
They can be enabled, except that then they will be skipped due to too old gdb.
Let me see if we can install 7.9 on the mips64 build machine.
