            Bug ID: 25846

ldconfig: Add --print-dirs option

Currently there's no way to know the exact search path that the dynamic loa=
der
uses. You can parse the entries in /etc/ld.so.conf (following any include
statements), but that doesn't include the "standard" builtin directories. A
good guess can be made with /lib and /usr/lib, but ultimately it depends on=
 how
glibc was built. This can often miss things like /usr/lib64 or
/usr/lib/$(arch_triplet) in common use.

There should be a method to obtain the directories that the dynamic loader
searches. This would also absolve users from having to parse /etc/ld.so.con=
f in
an error prone way. This information is particularly useful to tools that d=
eal
with building or installing libraries such as libtool.

The attached patch adds an option to ldconfig to handle this.
