   3 Description: Make output of build id optional
   4  With free software, anyone can inspect the source code for malicious flaws.
   5  But the software is often provided as binary packages to its users. The idea
   6  of “deterministic” or “reproducible” builds is to empower anyone to verify
   7  that no flaws have been introduced during the build process by reproducing
   8  byte-for-byte identical binary packages from a given source.  See also:
   9  https://wiki.debian.org/ReproducibleBuilds
  10  .
  11  Prior to this change a timestamp generated at build time is included in the
  12  output of 'smcroute -v'. As a result the binary is unreproducible.
  13  .
  14  With this change, users that still want 'smcroute -v' to include a build id
  15  can run './configure --enable-build-id' to get the build id back (or even
  16  specify a custom build id).
