Fix :hexadecimal_floating_point on i386

Browse Source 
Don't exclude i386 from LDBL_MANT_DIG == 64; it works properly in
that case.

While here, replace strcmp + atf_tc_fail with ATF_CHECK_MSG for 2
reasons:
- Gather as many results as possible instead of failing early and
  not testing the rest of the cases.
- Simplify logic when checking test inputs vs outputs and printing
  test result.

Tested on:	amd64, i386
MFC after: 	1 week
