[RS6000] LE SFmode constants in toc

[Alan Modra]

ppc64 SFmode constants in the TOC occupy the first word of a dword.
For little-endian, we don't need to shift left.  Bootstrapped etc. and
committed as obvious revision 199646.

        * config/rs6000/rs6000.c (output_toc): Correct little-endian float
        constant output.
