Can't compile library for Android using Windows

godot-cpp 576bd17

The command scons platform=android target=template_release arch=arm64 -j1 produces this output

scons: Reading SConscript files ...

scons: building terminated because of errors.

For some reason, flags from the microsoft compiler are used. A similar command in my CI with linux is executed without problems.

I also am getting issues building android binaries on windows, however my error is not the same, it seems like the build system tries to pass an invalid argument to the linker
ld: error: unknown argument '--out-implib'

In OP, SCons is trying to use MSVC arguments with Clang. This is a problem that has occurred numerous times in godot-cpp's history.

@SeleDreams's issue is unrelated, as it's not caused by an argument that is passed to MSVC (MSVC always uses Windows-style / syntax for CLI arguments, not - or --).

[DmitriySalnikov]

It seems like --out-implib is the MinGW flag for creating a DLL

which is weird, because it properly was using the NDK toolchain as we can see from the logs (I just took the first lines of the log since the rest doesn't have errors apart from the linking one i posted earlier
