That file on Ubuntu 14.10 (I am running this here) does not have debug info:

 ~> objdump -h /usr/lib/x86_64-linux-gnu/libc.a | grep debug_

Can you check this on Debian?

Ubuntu splits off debug info into -dbg files. For shared libc it's
libc6-dbg.

But libc6-dbg has nothing about the static libc.
