The nixpkgs-unstable channel's programs.sqlite was used to identify
packages producing exactly one binary, and these automatically added
to their package definitions wherever possible.
Among other things fixes build failure against upstream gcc-10:
ld: accessctl.o:/build/siproxd-0.8.2/src/accessctl.c:37: multiple definition of
`configuration'; siproxd.o:/build/siproxd-0.8.2/src/siproxd.c:46: first defined here
