[bug-gsrc] Recommended way of generating sha256sum

[Henrik Sandklef]

hi

 Locally I just switched to using a new dist from alpha and generated 
the corresponding sha256sums manually. Works fine (and a lot of wrnings 
removed for the GNU Xnee package).

 Before pushing/comitting the new settings and sha256 into the main 
trunk I wonder if if anything has been decided on how to generate the 
sha256sums in a "formalised" way?
