Build date ends up embbedded in binary images, breaking reproducibility
of jpeg-tools and libturbojpeg. To enable reproducible builds, build date can be
specified during configuration, via "--with_build_date=<date>".
If SOURCE_DATE_EPOCH is specified we configure libjpeg-turbo with this value as
build date. Although the build date is a generic string, we keep it in the same
format YYYYMMDD.
