How exactly do you add the -O2 option?

> Reproduce steps:
> 0. platform: openSUSE Tumbleweed 20241029 - Kernel 6.11.5-1-default, riscv
> qemu vm, gcc-14.2.1, binutils-2.43.1.20240828-2
> 1. echo "int main(){}" >z.c
> 2. gcc -g -O2 z.c

plus -c

So this "reproduces" the warnings.

But I cannot replicate using the debugedit build/tests.
Is there a special way you are configuring/building and/or running make check?

If you are editing debugedit.at to explicitly add -O2 then please just don't do
that.
