Bug#1054169: ares 132-1 fails to build on many architectures

[Benjamin Drung]

Source: ares
Version: 126-3
Severity: serious
Justification: FTBFS
X-Debbugs-Cc: bdrung at debian.org

Dear Maintainer,

ares 132-1 fails to build on many architectures (like armhf, i386, etc):

```
 debian/rules clean
dh clean --sourcedirectory=desktop-ui
   dh_auto_clean -O--sourcedirectory=desktop-ui
 cd desktop-ui && make -j4 distclean
make[1]: Entering directory '/<<PKGBUILDDIR>>/desktop-ui'
../nall/GNUmakefile:123: *** unknown arch, please specify manually.. Stop.
make[1]: Leaving directory '/<<PKGBUILDDIR>>/desktop-ui'
```

dh_auto_build is called with arch='$(ares_arch)'. So dh_auto_clean
should be called with that parameter as well.
