The situation here is kind of weird.

added -DARM_ENABLED=$(usex arm).

But that isn't right for arm64 where ispc works too.

It's also wrong because ispc can do cross-compilation with -DDISPC_CROSS=ON, but users on amd64 won't be able to enable USE=arm easily to do that.

A user tested MYCMAKEARGS="-DARM_ENABLED=ON` and they were able to use ispc for development/a project of their own then.

They tried with `-DARM_ENABLED=ON -DISPC_CROSS=ON` too but it ended up not being needed, I think
