libsystem_symptoms.dylib missing in Xcode 8 : <p>I just updated to Xcode 8, and I can no longer build xml2-based applications.  If I build a simple file and try to build it as follows:</p>

<pre><code>c++ myapp.cc `xml2-config --cflags` `xml2-config --libs`
</code></pre>

<p>...I get the following error message:</p>

<pre><code>ld: file not found: /usr/lib/system/libsystem_symptoms.dylib for architecture x86_64
</code></pre>

<p>It doesn't matter what's in myapp.cc (mine is just a main routine that returns 0).  The root problem seems to be that Apple removed /usr/lib/system/libsystem_symptoms.dylib in Xcode 8, but many of the .tbd files in /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk/usr/lib still point to it.  Has anyone else run into a problem like this?</p>
