Just to clarify, this script and its resulting binaries are to assist 
bootstrapping armv7l.  I don't think anybody is considering it for 
anything beyond a one time rebuild of all the packages.

This does bring up an interesting point- right now the flag difference 
is simply '-mfloat-abi=hard'.  Is this the right flag for all armv7 
concerns?

That's pretty much the idea.  It's just to get armv7 built without 
having to tackle circulator dependency chains during bootstrap.

It would definitely alter checksums.  What other issues do you foresee?
