* Add option --source-date-epoch-default and implement for deb output.
This is the first step towards supporting bit-for-bit identical
output files given identical inputs.
Alas, Apple's ar is not too good at reading gnu ar archives,
so always use ar_cmd to find ar.
* deb: remove lines duplicated in a tragic merge conflict
Probably introduced by 62d0060178 and not removed by 500f0c052f
* Add options --source-date-epoch-from-changelog and --gem-stagingdir to support bit-for-bit reproducible gem -> deb conversion
In those cases where we can get the release date out of the changelog,
use it; otherwise fall back to the value given by SOURCE_DATE_EPOCH aka --source-date-epoch-default.
--gem-stagingdir is a bit of a kludge, only needed because no
compiler supports https://reproducible-builds.org/specs/build-path-prefix-map/ yet.
Could have been global option, but not sure any other package handler
invokes compilers? Could hoist it up later.
Also:
- Defer initializing staging_path so subclasses can sneak in new value
- gem: remove build files
* gem: handle a few more gem changelog variants
* gem: also remove mkmf.log; lets ffi, kgio, raindrops, and ruby-ldap build reproducibly.
* deb: don't expect diffoscope to be installed in /usr/bin. Lets it be found on mac.
* gem: document new options
