thanks

I am observing the problem reported by the op in any build (i.e., this is fully
reproducible) using pbuilder inside a clean wheezy chroot. Here, configure fails
as shown below, even though /dev/urandom appears to be fine:

dd if=/var/cache/pbuilder/build/cow.29648/dev/urandom of=/dev/null bs=1k count=1
1+0 records in
1+0 records out
1024 bytes (1.0 kB) copied, 0.000126361 s, 8.1 MB/s

configure:23921: ./conftest
Fatal: can't open /dev/urandom: Bad address
