Works on r600g, Turks XT / HD6670.
I'm running my whole system with Marek's / Gregory's fixed glthread
branch.
https://cgit.freedesktop.org/~mareko/mesa/?h=glthread
I have mesa_glthread=true in /etc/environment ;-)
Tested-by: Dieter Nützel <die...@nuetzel-hh.de>
Cheers,

Previously we were deleting the entire cache if a user switched
between 32 and 64 bit applications.
V2: make the check more generic, it should now work with any
platform we are likely to support.
V3: Use suggestion from Emil to make even more generic/fix issue
with __ILP32__ not being declared on gcc for regular 32-bit builds.
