> Thanks a lot! For some reason, crossbuilding for `i686` works fine (without applying your suggestion).

The dependencies is incorrect, I think, it's like
```
exe ----> lib -----> lsrc.c ----> gen-src.h ----> prototype
 `---> esrc.c
```
Where `esrc.c` should depend on `gen-src.h` but not declared so. and ninja decided to build `esrc.c` before `gen-src.h
The dependency graph will be generated by host machine so they should only depend on host meson/ninja.
