In general given that those artifacts built using *_FOR_BUILD should never end up in a .deb, the set of build flags do not seem really important, as long as their omission would not cause build failures. This was covered in <https://lists.debian.org/debian-dpkg/2023/11/msg00032.html>. The important part is that we cannot unconditionally set *_FOR_BUILD flags from the host ones or that would break with host specific ones. I guess we could special case the native build one and then copying them over, although this could incur build failures at this point in time. :/ I guess this might be in the context of blhc?
