These emails are source code patches in the "unified diff" format 
(http://en.wikipedia.org/wiki/Diff#Unified_format). In principle can use the 
'patch' utility to apply them to your copy of the code. However, it is more 
likely that you'll find using 'git apply' or 'git am' more useful when working 
in the context of a Buildroot git clone.
