Eep. We really should pick up this info during runtime instead of
during build time. We do want a reproducible build. And this will most
likely produce wrong information if the package build server is on a
different OS or release than the OS/release it is producing packages
for. uname -sm might be "stable", but probably not when cross-
compiling. But where does lsb_release come from? I don't have that on
my systems.

Cheers,

Mark
