Explicitly remove __SIZEOF_INT128__ macro definition. (#419)
CompCert does not support 128-bit integers, but the gcc and clang preprocessors do include support as part of its 'built-in'.
A common way of testing for 128-bit integer support is to check to see if `__SIZEOF_INT128__` is defined.
Eliminating this macro prevents software from believing that 128-bit integers are supported.
