return the extracted version attribute, or 'default' if no version
attribute was specified, or the value cannot be determined without
importing the module. The version is formatted according to the
requirement's version format (if any), unless it is 'None' or the
supplied 'default'.

If the name 'symbol' is bound to a constant value by the Python code
object 'code', return that value. If 'symbol' is bound to an expression,
return 'default'. Otherwise, return 'None'.
Return value is based on the first assignment to 'symbol'. 'symbol' must
be a global, or at least a non-"fast" local in the code block. That is,
only 'STORE_NAME' and 'STORE_GLOBAL' opcodes are checked, and 'symbol'
must be present in 'code.co_names'.

Patch the globals to remove the objects not available on some platforms.
XXX it'd be better to test assertions about bytecode instead.
