One can workaround it by appending to the end:
../../../../lib/liblldbTarget.a
Or by wrapping the libs into:
-Wl,--start-group ... --Wl,--end-group
It is a recent regression although I am not sure when it happened. `git bisect`
says D73517 <https://reviews.llvm.org/D73517> but it has bad reproducibility. I
understand it may be affected by optimizations/inlining etc.
