Subject: Fix tests output

ProteanOS's BusyBox is built without support for echo's -n option, so this
happens:

    if [ 'xamd64-linux-glibc' = 'xamd64-linux-glibc' ]; then \
    	oh-autotest; \
    fi
    make[1]: Entering directory `/usr/src/pkgconf_0.9.6-1/tmp/src'
    /bin/sh tests/run.sh ./pkgconf
    -n .
    -n .
    -n .
    [...]
    -n .
    -n .
    
    83 tests done. All succeeded.
    make[1]: Leaving directory `/usr/src/pkgconf_0.9.6-1/tmp/src'
