  I would make it something like 'make $PKG-prepare-patch'. That gives us 
the possibility to later add a PATCH_BACKEND variable that can be set to 
git, hg or quilt (or something else).

  I think more people (in particular, the buildroot developers) are 
familiar with git (or hg) workflows than quilt workflows.

  guilt combines the best features of git and quilt for this particular 
purpose, I think (not that I ever used guilt :-). quilt has the 
disadvantage that you have to add a file before modifying it - this is 
solved by guilt. git has the disadvantage that it is easy to loose your 
orientation in the middle of a rebase (with edits) - that is also solved 
by guilt.

  I'm also in favour of this feature. In fact, a long time ago I posted a 
patch to add a script to do the reverse: create a patch series from a git
