Thanks for the input.  In any case in which the reason not to use
compressed debug symbols is something to do with package builds, a
workaround of this form could be used.

Then, the only tool compatibility reasons not to use compressed debug
symbols are (i) tools that users who have the symbols installed want to
run; and (ii) complicated debhelper order-of-operation issues which make
it difficult to use the above workaround.

Given that the debhelper maintainer said that he doesn't mind whether or
not compression is turned on, I think we can eliminate (ii).

Looking back through the thread, the closest thing we have to (i) is two
bugs in Valgrind.  However, those bugs are both marked as resolved.

So, I conclude that we still haven't seen concrete tooling problems
which would give us good reasons to disable compression.
