[PATCH v2 0/4] Granular timestamps in packages

[Paul Spooren]

v2: Fix Shellcheck patch which would exit if TOPDIR isn't definied.
	Instead it should just exit if TOPDIR is defined but the `cd`
	fails.

Based on Jo's IRC statement below[1] I reworked the get_source_date_epoch
script to create reproducible builds even if the SDK is updated.

<jow> aparcar: I investigated that pacakge reproducibility issue a
	little bit
<jow> the problem is twofold
<jow> 1) ipkg-bild uses SOURCE_DATE_EPOCH which - in the
	case of SDK - is hardcoded to the SDK build time

This should fix part 1. HG is untested and I'd prefer to just remove it
from the script, it doesn't seem to be used anywhere anyway.

<jow> 2) depending on toolchain version etc. building
	the same package sources might generate different binaries (this
	seems to be the lesser problem atm)

Part 2 will be tackled in some later patches.
