math: Fix log10f on some ABIs

Browse Source 
The commit 9247f53219 triggered some regressions on loongarch and
riscv:

math/test-float-log10
math/test-float32-log10

And it is due a wrong sync with CORE-MATH for special 0.0/-0.0
inputs.

Checked on aarch64-linux-gnu and loongarch64-linux-gnu-lp64d.
