At one point, we proposed doing this via a linker- or assembler-oriented
extra "salt" parameter, which would be hashed into the buildid.  This
would most naturally be a n-v-r-a string, so the build is reproducible.
Such a salt could be naturally injected via an environment variable set
by rpmbuild.
