Ok, changed that.

I only tested on amd64 (with libc6 version 2.13-38). However, I measured
for a while now, the improvement doesn't seem to be very big: On average,
the needed user time for "apt-get source sl" changed from 26.383s to
26.152s – that's ~0.9% difference.
Not that much, so maybe this patch should be dropped? I didn't look at the
precise numbers before submitting this patch, just had a quick look – I'll
try to do that better in the future. :/
