    automake: always use correct path for aclocal.real
    
    Before this commit, it was assumed that aclocal.real is in the PATH. While
    this was fine for the normal build workflow, this led to some issues if
    
        make TOPDIR="$(pwd)" -C "$pkgdir" compile
    
    was called manually. The command failed with:
    
        /home/.../openwrt/staging_dir/host/bin/aclocal: line 2: aclocal.real: command not found
        autoreconf: /home/.../openwrt/staging_dir/host/bin/aclocal failed with exit status: 127
    
    After the commit, the package is built sucessfully.
