Trying to build micromath for a ESP32C3 (a riscv32imc-unknown-none-elf target) gives:

rust-lld: error: undefined symbol: fminf

I'm assuming this is because core::f32 and core::f64 expose min, but these use the fmin* intrinsics, which appear to not be exposed for the riscv32imc-unknown-none-elf target

Similar to #354 it appears that fminf needs to be exposed for riscv32imc-unknown-none-elf
