Generated binary name inconsistent between macos & windows (macos doesn't have .exe suffix)

[jaredly]

It would make scripts a lot simpler if all platforms generated the same binary name.

Is the fix as simple as changing

bsb-native/jscomp/bsb/bsb_ninja_native.ml

Line 474 in 95055be

let extension = if Ext_sys.is_windows_or_cygwin then ".exe" else "" in

to just be .exe all the time?

[bsansouci]

Yeah should be sufficient

[Schmavery]

will break lots of little existing scripts so lets do it as part of a bigger upgrade if possible
