The reason `*l` was chosen as opposed to `__*ieee128` was that (AFAIK)
`__*ieee128` exists only to help with transition from IBM long double. FreeBSD
never had it - even its powerpc64 port is on 64-bit long double and powerpc64le
is transitioning from 64-bit long double. So since we don't have the legacy of
IBM long double, we can just directly switch to `*l`. Moreover, all the other
FreeBSD-supported architectures are already on `*l` and won't switch from that.
It just seems much more complicated without any benefit.
