Re: contrib/gcc_update bug?

[Richard Earnshaw <rearnsha at arm dot com>]

This can happen if gcc_update is itself updated and the change includes an 
alteration in the list of things to touch.  Maybe gcc_update could be made 
intelligent enough to detect this; I don't know.  In the mean time, if 
gcc_update is changed by an update, it is best to run it again.
