Simon Atanasyan c5e99819f4 [Mips] Adjust float ABI settings in case of MIPS16 mode.
Hard float for mips16 means essentially to compile as soft float but to
use a runtime library for soft float that is written with native mips32
floating point instructions (those runtime routines run in mips32 hard
float mode).

The patch reviewed by Reed Kotler.
