ptxconfig: make reproducible builds configurable
Some PTXdist packages use SOURCE_DATE_EPOCH to make the build more
reproducible. Make this behaviour more configurable via a newly
introduced ptxdist options. And make it possible to disable the stable
SOURCE_DATE_EPOCH via 'ptxdist setup'.
By default, this will set SOURCE_DATE_EPOCH to the year and month of the
PTXdist version. Using the toolchain version and a custom value is also
possible.
Move setting SOURCE_DATE_EPOCH to the scripts that are evaluated just
before make is called. This way, the toolchain setup and validation already
happened. Otherwise ptxd_timestamp_toolchain() may fail early before the
relevant checks and errors.
Based on a patch from Florian Bäuerle <florian.baeuerle@allegion.com>
