[Buildroot] permissions of downloaded source

[Danomi Manchego]

Yann,

Apologies if this was already addressed - I didn't follow all of the
download helper re-org threads ...

Using mktemp in the download help scripts means that downloaded
archives have 600 permissions.  On purpose?  This seems not so good
when groups use a shared "dl" directory.  Maybe these lines in the
download helper scripts:

mv "${tmp_output}" "${output}"

should be:

install -m0644 "${tmp_output}" "${output}"

?

Danomi -
