What is the expected behavior?

What went wrong?
build

Did this work before? N/A 

Chrome version:   Channel: n/a
OS Version: 
Flash Version: 

Adding the following packages fixed the link failures for me:
libxcb-dri2-0
libxcb-dri3-0
libxcb-present0
libxcb-sync1
libxshmfence1
libaudit1

But I don't know if only Aarch64 needs these packages or all platforms and I don't have the power to update the downloadable sysroots too, so I let you to fix this issue.

( note: I got these errors after fixing https://bugs.chromium.org/p/chromium/issues/detail?id=667283 and there is one more build error after adding these packages, but it is unrelated to the sysroot, so I'm going to file a separated bug report for it.)
