[Buildroot] [PATCH] Add support for local packages through 'file://' pseudo-protocol

[david.wagner at free-electrons.com]

	Hi,
I needed that feature ("downloading" tarballs that are already on my computer)
for a package that wasn't easily available as a tarball and I thought I might
not be the only one to need it. 

I hope the format of the submit is correct ; it's the first time I use git
send-email.

Regards,

[Buildroot] [PATCH] Add support for local packages through 'file://' pseudo-protocol

[david.wagner at free-electrons.com]

From: David Wagner <david.wagner@free-electrons.com>

Can be useful to integrate a home-made project or for testing purposes.
The default command to retrieve files is 'cp' but 'rsync' could also be used.
Through sshfs, it should also be possible to get non-public remote files on a
ssh server.

Sorry for the "raw" format of this submit. I guess I haven't figured out
yet how to add an introductory text with git send-email.

I needed the submitted feature to add a tool that wasn't easily
available as tarball (logfsprogs: Thomas showed me how to override the
download method but I couldn't have figured it out otherwise). But there
are other use-cases, like the ones in the commit message.

I hope the patch is ok, tell me if not.
