"Error: unrecognized option -mfpu=neon" When Compiling Server Version on the Raspberry Pi 3B+

[ngreve]

I would like to run Godot as a server on a Raspberry Pi, so I tried to compile it natively. (Probably related to godotengine/godot-proposals#988 in some way)

Godot version:

3.2 branch
Commit: 3e2e214

OS/device including version:

Raspberry Pi 3B+ running ArchLinuxARM

Issue description:

When compiling with scons -j2 platform=server tools=no target=release bits=32 natively on the Raspberry Pi 3B+ the following error occurs:

Steps to reproduce:
Run scons -j2 platform=server tools=no target=release bits=32 on a Raspberry Pi B+ running ArchLinuxARM
