Public bug reported:

When cross-compiling with do_tools,  dh_shlibdeps needs to be told to
look in /usr/<target>/lib otherwise it will fail the build.

I am cross-building in ubuntu-xenial.git (master) on x86_64 for an armhf
target:

         archtriple=arm-linux-gnueabihf
         flavour=generic
         dpkg-architecture -t $archtriple -c fakeroot \
                debian/rules \
                binary-$flavour binary-perarch \
                AUTOBUILD=true \
                abi_suffix= \
                do_linux_tools=true \
                do_tools=true \
                do_tools_usbip=false \
                do_tools_cpupower=false \
                do_tools_perf=true \
                do_tools_x86=false

This will fail later with errors like:
  dh_shlibdeps -plinux-headers-4.4.0-15-generic
  arm-linux-gnueabihf-objdump: .../asn1_compiler: File format not recognized
  arm-linux-gnueabihf-objdump: .../extract-cert: File format not recognized

I have had success with a fix that adds a -l option to dh_shlibdeps as
per manual pages. (See attached patch)
