Fix external term format BIFs on floating point middle-endian machines
This complements 933e701 (OTP-10209).
Simple error example:
1> <<131,70,63,240,0,0,0,0,0,0>> = term_to_binary(1.0, [{minor_version,1}]).
** exception error: no match of right hand side value <<131,70,0,0,0,0,63,240,0,0>>
2> 1.0 = binary_to_term(<<131,70,63,240,0,0,0,0,0,0>>).
** exception error: no match of right hand side value 5.299808824e-315
But roundtrip always works:
3> 1.0 = binary_to_term(term_to_binary(1.0, [{minor_version,1}])).
