:-) Ah, OK. I thought that that was already the reason you
didn't match the vDSO using AT_SYSINFO_EHDR in your original patch.

Or even after the patch is in, and we can revert if build / test bots
find a problem. Seems like a simpler step that I don't think anyone
would object to ...

Seems like Jan-Benedict Glaw is running a buildbot that includes GDB:

http://toolchain.lug-owl.de/buildbot/

No idea what system that runs on, and whether he runs the testsuite
as well.

Sergio was also interested in setting up a GDB build bot.

There's the gcc compile farm too.

We should be able to filter those out though. Of course ideally we'd
just fix them to not be fuzzy...
