[Click] Broken click_chatter output after last commit on arm

[Roberto Riggio]

With the commit 850cc464a012595567d21eae4105ed9f44c9757d the output of 
click_chatter
is messed up: variables are truncated and text seems wrapped around. The 
bug appears
to be platform dependent. It works on x86 but not on arm (intel ixp4xx) 
so I'm not sure
if the bug is click related.
