Howto cross-compile to i686-unknown-linux-musl?

[chrda81]

Hi,

I'm trying to compile to the 32bit target architecture "i686-unknown-linux-musl" with mojo build --target-triple i686-unknown-linux-musl hello.mojo but got the following error:

/usr/bin/ld: i386 architecture of input file '/tmp/mojo_archive-3a1894a.a(hello.mojo.8.o)' is incompatible with i386:x86-64 output

I found this answer in a info channel:

If want compile the file as 32 bits, you can use:
ld -m elf_i386 -s -o file file.o

Is it possible to set the switch -m elf_i386 with the build options? I also tried to force a docker container to run the i386 architecture by using the flag --platform=linux/386, but then mojo cannot be installed. Maybe there is no i386 binary available for download?

Could you please give me a hint to achieve that compilation target?
