Subject: [ 09/12] powerpc: Use -mtraceback=no

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Anton Blanchard <anton@...ba.org>

commit af9719c3062dfe216a0c3de3fa52be6d22b4456c upstream.

gcc 4.7 will be more strict about parsing the -mtraceback option:

 gcc: error: unrecognized argument in option '-mtraceback=none'
 gcc: note: valid arguments to '-mtraceback=' are: full no part

gcc used to do a 2 char compare so both "no" and "none" would
match. Switch to using -mtraceback=no should work everywhere.
