python: Add the needed patches to compile python2.7 in buildroot.

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.
