x86_64 has a different long double format; those 5 and 6 are the same as
other ldbl-128 architectures. I think of a rule of thumb as being that
ulps should be below 10. (Actually, except for IBM long double in
directed rounding modes, where we still need resolution on either putting
suitable versions of the libgcc functions in glibc or adding *_round /
*_ieee functions to libgcc that are enabled by suitable options, and
except for m68k where probably some long double functions need their
accuracy improved, all ulps are 7 or less.)
