LibC: Don't include fenv.h from float.h

This fixes a build issue where `compiler-rt` tried to declare its own version of the `FE_*` macros, and included `float.h` in order to get the constants. `compiler-rt` tried to declare these as an enum, and failed with a syntax error when the constant's literal values were substituted.
