I've come to not like compile time timestamp showing up in output as well.
Complicates CI tests checking for behavior regressions, defeats rsync's
--hard-link option if one uses that to keep backups of past CI builds, etc.
In short term and to prevent breaking our ABI, I suggest changing that
field to be NULL in both git and patch against debian. sox.c looks for
NULL and handles gracefully.
In longer term, I think a better plan is to output something like 'gcc -v'
outputs; the exact list of options pasted to configure script. That, I
think, is main intent of these timestamps; simple way to help detect 2
binaries reporting same version # but compiled with different
options/behavior.
