[rb-general] advice on stashing compiler options in a binary

Indeed. I have so far failed to come up with any kind of cleaner
solution when fixing packages affected with this "meta"
reproducibility issue beyond stripping them out with a regular
expression.

Of course, this approach is not only aesthetically displeasing, it is
practically problematic too in that one is always potentially playing
catch-up with GCC with new/updated flags. For example, you don't also
mention the parallel -ffile-prefix-map flag which also needs stripping.


Best wishes,
