Subject: [PATCH] Reproducible issue for libjpeg-turbo

[Message part 1 (text/plain, inline)]

Hi!
While conducting a study inspired by the "reproducible builds" practice [1], we have noticed that the package libjpeg-turbo could not be built reproducibly.

After investigation, we observe that the unreproducibility is caused by the "configure" script, in which the output of `date` is captured. 

The attached patch substitutes the `date` according to the SOUR_DATE_EPOCH.  Once applied, libjpeg-turbo could be built deterministically.
