Elliott Hughes ab2d3e1049 Remove __RENAME_LDBL.
Discussion of this during my recent minor cleanup convinced me that we
should just remove __RENAME_LDBL. There's no obvious benefit to being
able to build something for 32-bit if you can't build the same code for
64-bit, given that most new hardware (and entire verticals such as Auto)
are 64-bit-only, and the Play Store requires any app with 32-bit code to
also ship 64-bit code.
