Danomi, All,

Yes, the permission problem is already known, and I have sybmitted a new
series to fix this, and further enhance the download support, see;
    http://lists.busybox.net/pipermail/buildroot/2014-July/thread.html#102526

Although it seems OK at first sight, it misses a few corner cases.

First, the user's umask is not accounted for in the above. We do not
want to create files with more permissive permissions than the user
decided with his umask.

Second, the local-files download helper may have to copy files with the
executable bit set, and this is also missing in the install command
above.

Those two are handled in the series I posted. It is still open for
comments, though, so feel free to reply to it. ;-)
