With these two patches the flag *should* be honoured.  I don’t
understand yet where the rds differences come from, but I’ll

R 3.3.2 already includes the patches that were posted on Debian bug

r-build-system to pass down the flag to R packages.

properly (without grafts), so I thought everything was fine already.
