I am trying to link against xml2 by getting the flags from `xml2-config`.
$ xml2-config --libs
-L/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk/usr/lib -lxml2 -lz -lpthread -licucore -lm
In this directory I see corresponding .tbd files for each of the libraries, but some .tbd files refer to `/usr/lib/system/libsystem_darwin.dylib` in their re-exports section. The problem is that this file is missing in /usr/lib/system.
If I match the files in /usr/lib/system/ and the system/ directory inside the above directory, I see libcorecrypto_trace.dylib missing as well.
Does anyone what is happening here?
