As you can see in the lines I quoted above, your compiler does not
recognize the minimum-CPU-to-run-on (-march=<some ARMv7 flavour>) and
best-CPU-to-run-on (-mtune=<Cortex-M7, i.e. what's inside your STM32>)
values it's being passed, and the ones it says it will recognize are
all x86 microarchitecture names.

This means that you (or your IDE) is trying to compile your ARM code
with an x86 compiler.  You should see if your IDE came with a prebuilt
ARM compiler (otherwise you'll need to download or build it), and once
you're sure you have a compiler you should figure out why the IDE is
not finding it and trying to use the x86 one instead.

(Here by "an X compiler" I mean "a GCC compiler binary that runs on
your development machine and generates binaries for X".)

Because your problem is not with configuring GCC itself but with
configuring your IDE to use GCC, you're unlikely to find help on this
list;  if you're unable to figure out the configuration yourself, try
posting your question somewhere people actually talk about
STM32CubeIDE---probably the ST forums?

(Aside:  Usually, when you're experiencing some sort of general build
misconfiguration, *all* compilation will fail, so the length of the
build log will be multiplied by the number of parallel build jobs
you've allowed.  If you're seeing that nothing compiles, like here,
it's usually helpful to first retry with parallel building disabled,
not because it will fix anything, but because you won't have to dig
your way through a monster log like the one you posted.)
