Damien George 8e591d412a minimal: Make build more flexible and work as 64-bit build.
Changes are:
- string0 is no longer built when building for host as the target, because
  it'll be provided by the system libc and may in some cases clash with the
  system one (eg on OSX).
- mp_int_t/mp_uint_t are defined in terms of intptr_t/uintptr_t to support
  both 32-bit and 64-bit builds.
- Configuration values which are the default in py/mpconfig.h are removed
  from mpconfigport.h to make the configuration a bit more minimal, eg as
  a better starting point for new ports.
