By writing the fxc and dxc output to a temporary file and then
converting that temporary file to the desired filename, we avoid
the incompatible semantics of sed -i on GNU systems (sed -i does not
create a backup filename, and does not take an argument unless it is
"bundled") and macOS (sed -i requires an argument, possibly empty).

We require stdbool.h in the build environment, so we might as well use the plain bool type.
If your environment doesn't have stdbool.h, this simple replacement will suffice:
typedef signed char bool;
We want `$USE_FXC` to default to the result of evaluating the variable
`$HAVE_FXC`, not the literal string `HAVE_FXC`, and the same for dxc.
