[OE-core] [PATCH 1/1] python: gcc optimization level 2

The qemu didn't support '-march=corei7 -mtune=corei7' and
gcc optimization level 3 '-O3' very well, in which the
/usr/lib64/python2.7/test/test_md5.py and
/usr/lib64/python2.7/test/test_sha.py failed.

So we use gcc optimization level 2 to instead.
