# 2) It is also possible to check dirname and skip private
# directories (public ones are /lib, /lib64, /usr/lib, and
# /usr/lib64). However, non-standard directories can be added
# via /etc/ld.so.conf (we can use our dump_ld_config helper
# to print non-standard directories). And another problem
# is hwcap-specific directories, e.g. /usr/lib/sse2 (for wich
# there is no helper yet).
# 3) It is even possible to skip ld(1)-only symbolic links:
# if basename matches lib*.so, and corresponding $f.* file(s)
# exist, then $f appears to be a compile-time symbolic link.
# However, /etc/ld.so.cache seems to include both sonames and
# non-soname lib*.so entries.
# 4) Check whether it is a system library.
