The report uses some additional color coding, marking packages different which

the ubuntu-toolchain-r/volatile PPA.
There is also a test rebuild with link time optimization turned on by default
(passing -flto=auto in CFLAGS/CXXFLAGS). Other distributions turned these
optimzations on by default, or are considering doing that.
