You have a clear discrepancy between gcc and binutils. As you're using Gentoo
sources and build procedure I suggest you report the bug to them.

--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
-mloongson-mmi was added to gcc in r9-3891.  While it was added to binutils in
2.32.

Basically if you are going to bootstrap GCC 9 or 10 with -march=loongson2f you
need a newer binutils than you currently have selected.

I switch binutils to 2.36.1, and compiled successfully. Thank you!
