+Python's configure assume than when cross-compiling the target has no
+support for long long int. This assumption breaks compilation later in the
+process. Since gcc handles long long support, we can change the value to
+assume that there is such support.

+The compileall script is used to compile to python bytecode all the modules.
+However, it relies on the struct package that is not built for the host
+python, thus crashing at execution when compiling the target python.
+When compiling, the removed code block is never executed, so we can safely
+remove it, removing in the same time the dependency on struct.
