By using calloc() instead of malloc() in a loop, libc does not have to keep around bookkeeping information for each single structure. This reduces maximum memory usage while processing vmlinux.o from 3153325 KB to 3035668 KB (-3.7%) on my notebooks "localmodconfig". Note this introduces memory leaks, because some additional structs get added to the lists later after reading the symbols and sections from the original object. Luckily we don't really care about memory leaks in objtool.
