Answer 1

Instead of upgrading to GCC 4.9, I was trying to find where the flag was defined and remove it. On Debian Wheezy, I found it in /usr/lib/python2.7/plat-x86_64-linux-gnu/_sysconfigdata_nd.py which belongs to the libpython2.7-minimal package. My solution was to replace all occurrences of -fstack-protector-strong with -fstack-protector within this file. Then pip install executed the correct build command.
