[Uniformbuffer3]

Godot version

System information

Issue description

Hi, i was trying to compile Godot 4 (master) on an Alpine machine and it compiles correctly until the last linking phase when it throws this error:

[ 96%] Linking Program bin/godot.linuxbsd.tools.64 ...
[100%] progress_finish(["progress_finish"], [])
[100%] /usr/lib/gcc/x86_64-alpine-linux-musl/11.2.1/../../../../x86_64-alpine-linux-musl/bin/ld: platform/linuxbsd/crash_handler_linuxbsd.linuxbsd.tools.64.o: in function `handle_crash(int)':

collect2: error: ld returned 1 exit status
scons: *** [bin/godot.linuxbsd.tools.64] Error 1
scons: building terminated because of errors.

On the Godot compiling guide are reported the necessary dependencies to build on Alpine, so i suppose it is a supported system, otherwise i'm sorry for the noise.

Thanks for the dedicated time, have a good day.

Steps to reproduce

Just compile Godot targetting/on a musl machine.
