OK, I see so I won't mess with debug builds then:)

But another question: I just compared the dependencies compiler flags
of the old and the new build and realized that for the old build we
use '-MMD -MP -MF -fpch-deps' but in the new build we only use '-MMD
-MF' (except for x86 which is the only platform in the new build where
we still use -fpch-deps). Is this intentional as well?

I think the omission of -MP may be related to "8072106: Properly
handle dependencies for deleted header files" which created the
corresponding targets manually. But what about '-fpch-deps', shouldn't
we always use it?
