Building with MinGW LLVM: "unknown argument: -nostdlib, -soname"

[ariankordi]

I'm trying to build for Windows ARM64 from Linux and this LLVM MinGW toolchain I got from https://github.com/mstorsjo/llvm-mingw seems to be the best choice.

However, I've tried on and off to build this, even with the x86_64 version, and it keeps showing me this (I've tried versions going back to 2018 and it shows the same thing):

arian@debian /d/s/glew (master)> PATH=/dev/shm/llvm-mingw-20240417-ucrt-ubuntu-20.04-x86_64/bin/:$PATH SYSTEM=linux-mingw64 make

lld: error: unknown argument: -nostdlib
lld: error: unknown argument: -soname
make: *** [Makefile:123: lib/glew32.dll] Error 1

If I remove -nostdlib and -soname, it shows me this:

arian@debian /d/s/glew (master)> PATH=/dev/shm/llvm-mingw-20240417-ucrt-ubuntu-20.04-x86_64/bin/:$PATH SYSTEM=linux-mingw64 make

ld.lld: error: <root>: undefined symbol: _DllMainCRTStartup
make: *** [Makefile:123: lib/glew32.dll] Error 1

I know that the linux-mingw64 config assumes GCC and this is probably clang, but I'm not sure what modifications to make.
