Implement ldconfig functionality for ELF. The hints are stored in a different file than the a.out hints, namely, "/var/run/ld-elf.so.hints". These hints consist only of the directory search path. There is no hash table as in the a.out hints, because ELF doesn't have to search for the file with the highest minor version number. (It doesn't have minor version numbers at all.) A single run of ldconfig updates either the a.out hints or the ELF hints, but not both. The set of hints to process is selected in the usual way, via /etc/objformat, or ${OBJFORMAT}, or the "-aout" or "-elf" command line option. The rationale is that you probably want to search different directories for ELF than for a.out. "ldconfig -r" is faked up to produce output like we are used to, except that for ELF there are no minor version numbers. This should enable "ldconfig -r" to be used for checking LIB_DEPENDS in ports even for ELF. I implemented the ELF functionality in a new source file, with an eye toward eliminating the a.out code entirely at some point in the future.

extern int insecure; /* -i flag, needed here for elfhints.c */
Add a "-i" option ("insecure") which disables the checks for root ownership, etc. I will soon commit a companion knob for "/etc/rc.conf". Submitted by: Maxime Henrion <mhenrion@cybercable.fr>
