While fiddling with clang (upgrading it and applying some miscompilation patches), my mac LTO builds started to fail because ld64 would crash during configure. It turns out, it was crashing trying to print a warning it shouldn't even print out, about failure to create a cache path. This, in turn, is due to a pointer not being initialized in the ld64 code. I sent this upstream, and this was promptly fixed: https://github.com/tpoechtrager/cctools-port/pull/57 However, since our last update of cctools-port, upstream landed a change that broke support for tbd files if you don't compile against the new libtapi library. Doing so is more work than I'm ready to put here, so we just cherry-pick the fix.
