Description

I'm trying to get mi-malloc working in a x32 linux env and I've got an error:
```
make[2]: *** [CMakeFiles/mimalloc-static.dir/build.make:173: CMakeFiles/mimalloc-static.dir/src/alloc.c.o] Error 1
make[1]: *** [CMakeFiles/Makefile2:184: CMakeFiles/mimalloc-static.dir/all] Error 2
/root/src/mimalloc/include/mimalloc-internal.h: Assembler messages:
/root/src/mimalloc/include/mimalloc-internal.h:703: Error: operand size mismatch for `movq'

```

Research direction

Reproduce the failure with the x32 Linux ABI using the CMake build, then inspect include/mimalloc-internal.h around line 703 and the assembler diagnostic. Done means mimalloc-static compiles successfully in that environment without the operand-size mismatch.
