[libcall] Update musl Makefile to include missing files.

[lialan]

llvm/llvm-project#168622 changed how frem is lowered.
Instead of calling fmodf directly, it now expands frem using frexpf, ldexpf, and rintf.

• added those files in the Makefiles.
• re-compiled bytecodes with latest llvm binary: 65dd29b335ce6

This is needed to remove the revert in the integration #22856

This PR can fix the error I came across during LLVM integration as shown below:

With the change from this PR, we can drop the revert of llvm/llvm-project#168622 in the next LLVM integration.
