  Avoid encoding full build paths into headers, just use the basename of the file.
This aids build reproducibility where the build paths vary and source is saved
for debugging purposes.

I think this patch is at risk of being lost. It is a simple change
which aids reproducibility so I'm hoping someone might be able to help
with review/merging?

Thanks!
