[darwinbuild] Tokend build

[Ben Zhu]

Kevin, 

For BUILD 8F46, I am building the Tokend, I got an error when
darwinbuild runs to Mounting volfs:

Dyld: :ibrary not loaded: /usr/lib/libgcc_s.1.dylib
   Referenced from /sbin/mount_volfs
   Reason: image not found

At the end, an error message:

Xcodebuild: Error: the directory /SourceCache/Tokend/Tokend-11 does not
contain an Xcode project.


Do we have a patch for this error fix?

Thanks,

Ben
