Title: Fix CFLAGS in tox.ini

Without this fix gcc 4.9 (the default C compiler on Ubuntu 14.10) aborts with
the following error:

cc1: error: unrecognised debug output level " -O0"

As far as I can tell this happens because "-g -O0" is passed as a single
argv[] entry to the C compiler.

The 'setenv' parameter in tox.ini is not shell code, it doesn't need to be
quoted (and spaces around '=' are also okay[*], so I added them, to make it
apparent this is not shell syntax).
