+Subject: Add optimization to cflags in sysconfig.py when building C modules.
+
+When compiling C code using python, the resulting binary is not being optimized
+properly. Currently this is caused by the 'OPT' variable never being imported or
+used in distutils/sysconfig.py and not being appended to the cflags variable.
+This patch fixes the issue by importing 'OPT' and appending it to 'cflags'.
