 Doesn't this reintroduce the failure fixed with commit a79a404e6c22 
("MIPS: Fix CONFIG_CPU_DADDI_WORKAROUNDS `modules_install' regression")?

 If this call to `cc-option-yn' does need to be made here, then this whole 
stuff has to be wrapped into a `need-compiler' check, see the discussion: 
<https://lore.kernel.org/r/alpine.DEB.2.21.2307180025120.62448@xxxxxxxxxxxxxxxxx/> 
and the other patches in the series.
