For the default multilib settings, it looks like you just intended to
use -mcustom-fpu-cfg=60-2. I suggest you modify t-rtems to do that
instead of enumerating the individual FPU insn options.
Other than that, the patch looks okay.

From the documentation
https://gcc.gnu.org/onlinedocs/gcc-4.9.1/gcc/Nios-II-Options.html#Nios-II-Options
we have
-mcustom-fpu-cfg=60-2 is equivalent to:
-mcustom-fmuls=252
-mcustom-fadds=253
-mcustom-fsubs=254
-mcustom-fdivs=255
-fsingle-precision-constant
This is NOT what I want. I don't want this -fsingle-precision-constant.
