Since we’re about to freeze ‘core-updates’ and I’d like to make progress
on this front, I pushed the ld-wrapper change as commit
696487d665a616dfdd09272a7bff0bea0e19375d.

It’s not perfect as discussed earlier, but it’s known to be “good
enough” with GHC and Chromium, which are the only users of this I know
of.

Thanks,
Ludo’.
