I think it would make sense to add try-run, cc-option and
.DELETE_ON_ERROR to tools/build/Build.include?

To be safe, I just copy-pasted what the makefiles need.
If someone wants to refactor the tool build system, that is fine,
but, to me, I do not see consistent rules or policy under tools/.

"Please put this in a common file instead of introducing duplication" is 
not asking for wholesale refactoring.
