Hi!. We are studying using mimalloc as the malloc for julia. While doing this, we found an error on musl, where if you statically link mimalloc to a shared library, then dlopen it. You get Error relocating /workspace/mimalloc/build/test.so: __errno_location: initial-exec TLS resolves to dynamic definition in /workspace/mimalloc/build/test.so.

While the issue is simple enough to solve in our case, just build it with -DMI_LOCAL_DYNAMIC_TLS=ON on musl, it would be more correct if the build system detected it was targeting musl and did that automatically.
