2021-06-05build system: use SOURCE_DATE_EPOCH for timestamp if availablePaul Spooren
The SOURCE_DATE_EPOCH is an effort of the Reproducible Builds organization to make timestamps/build dates in compiled tools deterministic over several repetitive builds. Busybox shows by default the build date timestamp which changes whenever compiled. To have a reasonable accurate build date while staying reproducible, it's possible to use the *date of last source modification* rather than the current time and date. Further information on SOURCE_DATE_EPOCH are available online [1]. This patch modifies `confdata.c` so that the content of the SOURCE_DATE_EPOCH env variable is used as timestamp. To be independent of different timezones between builds, whenever SOURCE_DATE_EPOCH is defined the GMT time is used.

2013-07-26buildsys: Add helper to list suid appletsBernhard Reutner-Fischer
Add a helper script that lists all applets that - do or may require SUID provileges (busybox.cfg.suid) - do not require SUID provileges (busybox.cfg.nosuid) Some setups prefer to build two busybox binaries, one that is suid which contains all applets that do or may require suid privileges, and a second one for all the rest (which drops suid). To ease splitting these two binaries, generate a list of CONFIG_ items for the suid binary. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
