Can't create build image on ARM (m1) Mac

[Emstr]

I'm struggling to create a build image on my M1 MacBook Pro.

After I run ./build-showmewebcam.sh raspberrypi0w I get the console output:

Using configs/config as base
Merging configs/raspberrypi0w
cp: illegal option -- T

cp [-R [-H | -L | -P]] [-fi | -n] [-apvXc] source_file ... target_directory

merged configuration written to configs/raspberrypi0w_defconfig (needs make)

You must install 'gcc' on your build machine
make[1]: *** [dependencies] Error 1
make: *** [_all] Error 2

However, I do have gcc installed. gcc -v returns

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/4.2.1

I think this appears to be an issue with the arm64 version of gcc? When I try to manually run the Makefile using gcc I get the error:

emoryfierlinger@emorys-mbp showmewebcam % gcc /Users/emoryfierlinger/showmewebcam/output/raspberrypi0w/Makefile
ld: warning: ignoring file /Users/emoryfierlinger/showmewebcam/output/raspberrypi0w/Makefile, building for macOS-arm64 but attempting to link with file built for unknown-unsupported file format ( 0x23 0x20 0x41 0x75 0x74 0x6F 0x6D 0x61 0x74 0x69 0x63 0x61 0x6C 0x6C 0x79 0x20 )
Undefined symbols for architecture arm64:

ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Any help would be greatly appreciated

I got this issue when i try to compile the project on my M1 Mac without any virtualization, after some searching, found this great document to cross-compile linux kernel on Mac from @geerlingguy

You can fire up that docker image, and try compile the project again with that docker image
