Bug#1019298: spacenavd: FTBFS on all platforms

[Eric Long]

Source: spacenavd
Version: 1.0-1
Severity: serious
Tags: ftbfs patch
Justification: fails to build from source (but built successfully in the past)
X-Debbugs-Cc: i at hack3r.moe

Dear maintainers,

spacenavd v1.0-1 failed to build on all platforms:

```
/usr/bin/make cleandep
make[2]: Entering directory '/<<PKGBUILDDIR>>'
make[2]: *** No rule to make target 'cleandep'.  Stop.
make[2]: Leaving directory '/<<PKGBUILDDIR>>'
make[1]: *** [debian/rules:15: override_dh_auto_clean] Error 2
```

Full buildd log: https://buildd.debian.org/status/logs.php?pkg=spacenavd&ver=1.0-1&suite=sid

I've submitted an MR [1] that removes unnecessary `override_dh_auto_clean` and
fixes FTBFS. Please let me know if I missed anything.

Best regards,
Eric
