Fix cross compilation problem in parse-types.sh

The checking of types in parse-types.sh doesn't make much sense in a
cross-compilation environment, because the generated binary is
executed on build machine.

So even if asm_types.h has got correct statements for types, it's
possible that the generated binary will report an error, because these
types are for the target machine.
