That's not a given for musl, quite the opposite. I would expect it to
last at most a release cycle, possibly even to disappear before then
if distros backport the changes to their development branches early
and find and fix everything.

It's a simple fix, but the question is how many such simple fixes a
distro might need to make in their packages, and that I don't know.

If they have a trivial mechanical fix of "add something to CFLAGS"
they can do at first, that lets them build a list of affected packages
while quickly getting them all building again, then work out the right
fixes one at a time according to usual triage rather than being
swamped with these taking priority over issues with more depth.
