Clint Byrum d9a2211d14 Only use tmpfs if build machine has 4GB+ RAM.
For machines with low RAM (or no access to /proc/meminfo) the builder
will still run, but will just build inside the filesystem that is
hosting /tmp. This will result in a slower build (especially if there
are a lot of .deb packages installed).

Fixes bug #1175453
