Title:
  wrong compiler flags in _sysconfigdata.py

Status in python2.7 package in Ubuntu:
  Incomplete

Bug description:
  The package `libpython2.7-minimal` (versino 2.7.9) installs `/usr/lib/python2.7/plat-x86_64-linux-gnu/_sysconfigdata_nd.py` which has unsupported `gcc` flag, for example:
  ```
  >>> import _sysconfig
  >>> _sysconfig.build_time_vars['LDSHARED']
  'x86_64-linux-gnu-gcc -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions -Wl,-z,relro -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -D_FORTIFY_SOURCE=2 -g -fstack-protector-strong -Wformat -Werror=format-security '
  ```
  contains `-fstack-protector-strong` which is not supported by the `gcc` shipped with ubuntu 14.04 (version 4.8.2-19ubuntu).  I found it when I tried to install `pygit2` using `pip` (for that one needs to compile `libgit2-0.22.0` from sources, since ubuntu ships `libigt2-0.19.0`. `gcc` was failing with an error because `-fstack-protector-strong` is not supported.  After replacing the flag with `-fstak-protector` `gcc` runs smoothly.
