  -----------
  q3rcc: Allow to override build date

Allow to override __DATE__ and __TIME__ with SOURCE_DATE_EPOCH
in order to make builds reproducible.
See https://reproducible-builds.org/ for why this is good
and https://reproducible-builds.org/specs/source-date-epoch/
for the definition of this variable.

This behavior is what gcc already does.
