Log Message:
{x86,m68k}/float.h: document LDBL_MIN behavior

It seems that even though both these platforms have 12-byte floats
that are pretty much the same representation and both allegedly
IEEE-compliant, they manifest the top bit of the mantissa and then
differ slightly in the behavior of the extra encodings this permits.

Thanks to riastradh@ for helping sort this out.
