Comment (by gk):

 Okay, I think that both problems you encountered are actual `libbacktrace`
 bugs. `libbacktrace` treats similar `dl_iterate_phdr` issues by making
 sure `HAVE_DL_ITERATE_PHDR` is not defined. That's essentially what the
 Rust folks did when updating `libbacktrace` for 1.28.0, so I think
 following that path is okay. I attached a patch for that.

 I am not sure yet what's up with `getpagesize` but I think your approach
 is right using `sysconf(_SC_PAGESIZE)` instead.

 Additionally, it seems we don't need the `ar` related option in
 `configure_opt` either. Could you remove that one (+ the linker related
 one) and add a `dl_iterate_phdr` + `getpagesize` patch in a separate
 commit? And on top of that one the one we thought for this bug? (I think
 everything you had was good, just the API line in the `mozconfig-android-
 armv7` file should go aswell).

 My current plan is to not spend more time on this issue (although it's
 weird that Mozilla did not run into those problems). I already shaved
 enough yaks to get that far. :)
