It is a pain in the ass to compare the software versions on the running
system (scripts/ver_linux) with the minimal required versions (changes.rst).
Sorting both lists the same way makes side-by-side comparisons a simple task.

 [v2] -> [v3]:
fix changelog
changes.rst:
 needn't -> do not need to
 add gdb 7.2
ver_linux:
 /Changes.rst -> /changes.rst
 add gdb

 [v1] -> [v2]:
split v1 into a patch series
changes.rst:
 add reference to ver_linux
ver_linux:
 fix path to changes.rst
