Linux: Drop ppc32 (32-bit PowerPC) architecture support

Browse source 
This was added together with `ppc64le` in #54490, but seemingly only for the
purpose of getting it to compile on a Linux distro that aims at maximizing
support for all CPU architectures.

I don't think anyone has ever _run_ Godot on a `ppc32` system (do those even
support OpenGL ES 3.0?) and so I don't think we should aim to support it.

Debian dropped support for its PowerPC (`ppc32`) arch in Debian 9, released
in 2017.
