buildsys: Add helper to list suid applets
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>
