Maciej W. Rozycki 963d6c79ea RISC-V: Fix floating-point environment support for soft float 
We don't have floating-point exception or non-default rounding mode
support for the RISC-V soft-float environment, `feraiseexcept' and
`fesetround' do nothing unless the `__riscv_flen' macro has been set.
Therefore following ISO C language requirements[1] only define macros
for soft float that correspond to actually supported floating-point
environment features, removing failures from GCC testing such as:

FAIL: gcc.dg/torture/fp-int-convert-timode-3.c   -O0  execution test
FAIL: gcc.dg/torture/fp-int-convert-timode-4.c   -O0  execution test
