Linker error: undefined reference to `__mulodi4'

1. Configure qtbase on a 32-bit machine.
   I used:

   ~/dev/src/qtbase/configure -platform linux-clang-libc++ -no-opengl -sanitize address -opensource -confirm-license -developer-build
   

2. Try building this.
   I used:

   cmake --build .
   

   The build will fail:

   [  3%] Linking CXX executable ../../../bin/moc

   I attached the full logs.

On a 64-bit machine, this works fine.
