- build against installed dependencies rather than in-tree dependencies

- don't build both static and shared libraries: pass either
  --disable-static or --disable-shared to configure.

- set TMPDIR to the tmpfs filesystem if /tmp is not already a tmpfs
  filesystem.

- don't enable SELinux at boot.
