Browse source 
The build id contains the build timestamp by default.
Make this field optional.
Build timestamp prevents reproducible builds [0].
Thanks to the debian project for the patch.

Description: Make output of build id optional
With free software, anyone can inspect the source code for malicious flaws.
But the software is often provided as binary packages to its users. The idea
of “deterministic” or “reproducible” builds is to empower anyone to verify
that no flaws have been introduced during the build process by reproducing
byte-for-byte identical binary packages from a given source. See also:
https://wiki.debian.org/ReproducibleBuilds
.
Prior to this change a timestamp generated at build time is included in the
output of 'smcroute -v'. As a result the binary is unreproducible.
.
With this change, users that still want 'smcroute -v' to include a build id
can run './configure --enable-build-id' to get the build id back (or even
specify a custom build id).
