Those package look like the ones someone else provides for OpenVPS
systems that require kernel 2.6.18.  Arch sets a minimum kernel version
of 2.6.32.  There is no way I made more than 100 releases of glibc-2.15!

Looking back at my glibc-2.15 packages, the main patching I did was to
fix issues caused by broken AVX detection, which would appear unrelated.

The last post in that forum thread appears to have an explanation:
https://bbs.archlinux.org/viewtopic.php?pid=1176560#p1176560.   In fact,
this thread corresponds the time where our toolchain was built against
Linux 3.3 headers (update from 3.1).  So this is probably the cause.
