Subject: [PATCH] harvid: fix pending upstream inclusion to support parallel
 builds

Without the change parallel build fails as:

    make -C src
    make[1]: Entering directory '/build/harvid/src'
    ld -r -b binary -o seek.o ../doc/seek.js
    ld -r -b binary -o logo.o ../doc/harvid.jpg
    make[1]: *** No rule to make target '../libharvid/libharvid.a', needed by 'harvid'.  Stop.
