[FB-Tracker] Created: (CORE-5548) firebird does not build reproducibly

JIRA tracker@firebirdsql.org
firebird does not build reproducibly
------------------------------------

                 Key: CORE-5548
                 URL: http://tracker.firebirdsql.org/browse/CORE-5548
             Project: Firebird Core
          Issue Type: Bug
    Affects Versions: 3.0.1
         Environment: OS=Linux (openSUSE Tumbleweed)
            Reporter: Bernhard M. Wiedemann


When working on reproducible builds for openSUSE,
I found that the firebird package produced different results on every build.

The differences come from two sources:

1.
g++ orders functions in libEngine12.so and fbintl
depending on random order of files in the build system's filesystem.

2.
Additionally, help.fdb and other sample .fdb files contain some bytes that differ between builds.

See https://reproducible-builds.org/ for why this matters.
