Incompatibility with ocaml-option-bytecode-only: Build fails on non-native-code architectures(eg, armel,i386)

[yuzibo]

With many people's help, lem was uploaded to Debian official.

But to my surprise, it build failed on many architectures, like arm{el,hf}, i386, misp64el with following log.

After more searching, I noticed there is one commit to stop building on bytecode support only from opam-repository.
So could you help me to confirm that is right?

If so, I can only enable build support on architectures with native code supported like x86, arm64, riscv64 and s390x from the buildd page. TIA.

Update:

Thanks to my sponsor's(glondu@debian.org) help, now there is one patch to support bytecode compiler build.

Would you like to add support for bytecode compiler? If so, I can open one PR to forward glondu's patch. thansks.
