mipsel-none-elf for macos

[VityaSchel]

Please release binary files for building with psn00bsdk on macos, it appears that everything is good until build process uses binary files such as mipsel-none-elf-gcc which obviously results in zsh: exec format error since binary files are for linux, not arm mac
Can you guide me to the right direction there?

I guess I should start with building toolchain myself
https://github.com/Lameguy64/PSn00bSDK/blob/master/doc/toolchain.md
and then the sdk itself

Update: I'm trying to build gcc but getting "too many errors emitted, stopping now". I tried

make CFLAGS="-w -Wno-error -fmax-errors=0" CXXFLAGS="-w -Wno-error -fmax-errors=0" -j 4

no flags help, it still stops make after 20 errors

Upd2: I tried gmake and it looks like it worked for a second but then I have another error:
ld: symbol(s) not found for architecture arm64 clang++: error: linker command failed with exit code 1 (use -v to see invocation) when installing
so I gave up

I managed to install mipsel-none-elf (binutils and gcc parts) from this project https://github.com/grumpycoders/pcsx-redux/blob/main/src/mips/psyqo/GETTING_STARTED.md#macos
It works and I can finally run mipsel-none-elf-gcc. After copying all bin executables from
/opt/homebrew/Cellar/mipsel-none-elf-gcc/14.2.0/bin and /opt/homebrew/Cellar/mipsel-none-elf-binutils/2.43/bin to psn00b SDK's bin folder and running make on one of the examples I still get error:

-- Configuring incomplete, errors occurred!

So look at this line: mipsel-none-elf-gcc: fatal error: cannot execute 'cc1': posix_spawnp: No such file or directory. I tried googling it but couldn't find anything.
My guess is that sdk.cmake is built specifically for linux, thus asking for cc1 or posix_spawnp or whatever else is exclusive to linux and not available on macos, won't work
So I guess I should compile the sdk.cmake somehow for macos? I will try https://github.com/Lameguy64/PSn00bSDK/blob/master/doc/installation.md#building-from-source

Still getting the same error when trying to compile psn00b sdk: posix_spawnp: No such file or directory
