<pre>
    When using `wasi-sdk` to compile a C file to `.s` and then to wasm32 `.o`, the second step would fail with an error message like this (compiling it to `.o` directly seems to be fine):

```
/tmp/ghc_1.s:630:2: error: symbol memset missing .functype
        call    memset
        ^
```

The command line to reproduce is:

```sh
clang -x c rts/Weak.c -o /tmp/ghc_1.s -fno-PIC -Wimplicit -S -O -include rts/include/ghcversion.h -Irts/include -I_build/stage1/rts/build -I_build/stage1/rts/build/include -Irts/include -I_build/stage1/rts/build -Irts -I_build/stage1/rts/build -Xpreprocessor -include -Xpreprocessor _build/stage1/rts/build/autogen/cabal_macros.h -Xpreprocessor -Wno-nonportable-include-path -Xpreprocessor '-DRtsWay="rts_v"' -Xpreprocessor '-DFS_NAMESPACE=rts' -Xpreprocessor -DCOMPILING_RTS -Xpreprocessor -DNOSMP -Xpreprocessor -DNOSMP -DUSE_MINIINTERPRETER -DNO_REGS '--target=wasm32-unknown-wasi' '--target=wasm32-unknown-wasi' '--target=wasm32-unknown-wasi' -Irts/include -I_build/stage1/rts/build -I_build/stage1/rts/build/include -Irts/include -Wno-unknown-pragmas -Wall -Wextra -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Winline -Wpointer-arith -Wmissing-noreturn -Wnested-externs -Wredundant-decls -Wundef -fno-strict-aliasing -fomit-frame-pointer -O2 -g -Irts -I_build/stage1/rts/build -DNOSMP

```

We tried `13.0.0`, `13.0.1` and `14.0.0-rc1` llvm revisions in the `wasi-sdk` build, the error persists. Since this only involves codegen and not linking with sysroot, I believe the repro can also work with a vanilla `clang` installation.

The commands can be run in the directory packaged in this tarball: https://drive.google.com/file/d/1ur9O8rQ0xYYLi8tmOlg79h7H0SXHPmw9/view?usp=sharing. We're still trying to come up with a minimal self-contained repro, meanwhile this is the best we have so far.
