More-compatible Linux standalone binaries

The binaries currently provided were compiled against glibc 2.11+, so
people using CentOS 5 (which has glibc 2.5) are not able to use them.

The binaries in this patch were compiled in VMs installed with CentOS
5.9, and so should work for more people; at a glance, it looks like
glibc 2.3 or later will probably work now.
