Hi all!

I am trying to build an amd64 Debian package from sources but the 
command dpkg-buildpackage -us -uc fails with a number of the following 
error messages:

ERROR: ld.so: object 'libfakeroot-sysv.so' from LD_PRELOAD cannot be 
preloaded (wrong ELF class: ELFCLASS64): ignored.

I have installed (and re-installed) the devscripts, fakeroot and 
build-essential packages but still get the error. The system was 
crossgraded from i386 to amd64 and still runs a mix of i386 and amd64 
but the build packages seem to be all amd64:

bilbo:~# dpkg -l | grep fake
ii  fakeroot 1.23-1                                amd64        tool for 
simulating superuser privileges
ii  libfakeroot:amd64 1.23-1                                amd64        
tool for simulating superuser privileges - shared libraries
bilbo:~# dpkg -l | grep devscripts
ii  devscripts 2.19.5+deb10u1                        amd64

bilbo:~# dpkg -l | grep build-essentila
bilbo:~# dpkg -l | grep build-essential

Is there anything else that I need to (manually) change?
