* Revert the URL out from cmake for libbacktrace * Switch git submodule to upstream HEAD instead As per discussed here apache#18246 (comment), this reverts in favour of git submodule way. As per finding in the same discuss the upstream [already](https://github.com/ianlancetaylor/libbacktrace/blob/793921876c981ce49759114d7bb89bb89b2d3a2d/macho.c#L1273-L1275) incorporates [the one patch](ianlancetaylor/libbacktrace@master...tlc-pack:libbacktrace:master) used, and MacOS works fine.
