Intel Galileo Boards won't install on python3 linux distributions

On Archlinux python3 is the default python. Possibly also on other distros sooner or later.

The file that gives the error is:
`.arduino15/packages/Intel/tools/i586-poky-linux-uclibc/1.6.2+1.0/i586/relocate_sdk.py`

The fix is simple:

``` diff
-#!/usr/bin/env python
+#!/usr/bin/env python2
```

I could not find the galileo files on github, so I report that here. Where can i find the sources for this except for my local copy?

Edit:
Those warnings should also get eliminated:

I am also not sure if the fix above solves all problems, but users also get this error:
https://paste.debian.net/889770/

Start with .arduino15/packages/Intel/tools/i586-poky-linux-uclibc/1.6.2+1.0/i586/relocate_sdk.py and investigate how the Intel Galileo package is sourced and installed on Python 3 Linux distributions. Reproduce the reported installation failure, then verify that the package installs successfully and determine whether the listed absolute-path warnings and the linked error remain.
