[OE-core] [PATCH v2 0/3] relocate_sdk.py: improvements

[Jason Wessel]

Now that I have had to debug the SDK relocator on multiple occasions
I figure it might be nice to get the patches upstreamed.  This last
time through fixing the python 2.4.x compatibility was very easy
using the prior two patches to allow me to do so.

The idea here is to increase the portability of the relocator because
once the SDK is installed/relocated, generally speaking it is working
well on old and new hosts.

Thanks,
Jason.
