>Description:
This issue affects FreeBSD 10 with clang as primary compiler (cc).

When compiling python configure script wrongly detects that system compiler
supports -OPT:Olimit=0 flag:

checking whether cc accepts -fno-strict-aliasing... yes
checking whether cc accepts -OPT:Olimit=0... yes

clang seems to ignore this flags and configure script comes to bad conclusion.

This breaks consumers using python-config scripts to get python cflags:

[corn:~]> python-config --cflags
-I/usr/local/include/python2.7 -I/usr/local/include/python2.7 -fno-strict-aliasing -OPT:Olimit=0 -O2 -pipe -fno-strict-aliasing -DNDEBUG

Olimit is there, while clang will be happy to ignore it, gcc will fail. I
discovered this trying to build print/lilypond.

Upstream bug: http://bugs.python.org/issue877121

lang/python32 and lang/python33 appears to be unaffected by this
