`__aeabi_d2h` is defined in the RTABI https://github.com/ARM-software/abi-aa/blob/main/rtabi32/rtabi32.rst#standard-conversions-between-floating-types . Strictly, but unhelpfully, speaking it is a bug that libgcc doesn't define it.

I can refer to this to our GNU team, but it even if fixed it would take some years to get into distros.
