cannot build LLVM for `x86_64-linux-muslx32`

[HomuHomu833]

Zig Version

0.16.0-dev.164+bc7955306

Steps to Reproduce and Observed Behavior

this caused in all versions of Zig (0.14 to 0.16-dev) and I tried to do research about R_X86_64_GOTTPOFF but I understood nothing about it and also I forgot to report multiple times.

Expected Behavior

to LLVM compile/build

[HomuHomu833]

oh really upstream issue? do I need to report to LLVM aswell?

[alexrp]

Probably. But I don't think there's an LLVM x32 maintainer nowadays, so don't get your hopes up.
