Is this a useful option?

(This option sometimes causes issues and I believe it should not
be necessary on Windows)

Why is this necessary?
Is there a bug we don't know about?
(Or just a bug in an external library?)

These are unneeded.

(I suspect there is no operating system with a command "Make")

Very generally, I would not expect the same non-trivial configure line
to work on
Linux and Windows (think of cross- vs native compilation).

In my tests, I saw some issues with wsl2, I recommend wsl (1)
for FFmpeg Windows compilation.
