SELinux support requires setting the appropriate SELinux security context
to files and directories, which needs to happen at build time in order
to support read-only root filesystem scenarios. In order to create these
security contexts, we will have to run some SELinux-specific tools on
the host machine, but that requires root access. This adds support for
fakeroot, which the build process will use to run the SELinux security
context creation and the image creation.

Remapping the local build path in debug information makes debugging
using ./scripts/remote-gdb harder, because files no longer refer to the full
path on the build host.
For local builds, debug information does not need to be reproducible,
since it will be stripped out of packages anyway.
For buildbot builds, it makes sense to keep debug information reproducible,
since the full path is not needed (nor desired) anywhere.

To keep the output reproducible in any case, we enforce a minimum amount
of 2 threads.
