Subject: Re: 32 bit musl?
As Rich noted, a cross-compiler is the easy way out here - GCC multilib has a number of assumptions that break under musl and likely elsewhere.
Since you seem unsure how to compile one, I’d recommend musl-cross-make[1].
You only need to edit a single variable in config.mak and run 'make && make install' to get a working toolchain.
