Not only that: this isn't a full fledged little-endian mode like `mipsel`. See "Oracle SPARC Architecture 2015", p.20:
3.3.1.2 Addressing Conventions
[...]
The Oracle SPARC Architecture also supports little-endian byte order for data accesses only: the
address of a quadword, doubleword, word, or halfword is the address of its least significant byte.
Increasing the address means increasing the significance of the data unit being accessed.
