summary:
Fix byte-compilation to comply with PEP 3147 on Python 3.2+ (#11254).
I want to replace custom byte-compiling function with calls to
compileall before 1.0, but in the short term it’s good to have this
fixed.
Adapted from the distutils patch by Jeff Ramnani. Tested with -B, -O
and -OO on 3.1, 3.2 and 3.3.
