Sure! Why not? Or it just removes this line entirely because of this: 

```
# Determine default set of targets to build -- the intersection of                                                                                                                         
# those BOLT supports and those LLVM is targeting.                                                                                                                                         
set(BOLT_TARGETS_TO_BUILD_all "AArch64;X86;RISCV") 
```

But if you worry about the cognitive effort that might be hard to understand as you demonstrated in your case:

"AArch64;X86;RISCV  archs is supported!"
