Subject: [PATCH] buildscript: count available cpus with nproc
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Grepping `/proc/cpuinfo` does not yield the correct number of available
cpus when running in a docker container or setting the number of
available cpus with taskset.

```
$ taskset 1 grep -c processor /proc/cpuinfo
8
$ taskset 1 nproc
1
```

This will prevent using too many build jobs on environments where the
number of available cpus is reduced.

`nproc` is part of `coreutils`.
