Subject: nsswitch: handle missing actions properly
Some internal functions need to know if a database has a nonzero
list of actions; success getting the database does not guarantee
that. Add checks for such as needed.
Skip the ":" in each nsswitch.conf line so as not to add a dummy
action libnss_:.so

Short description: Work ld.so --verify crash on debuginfo files.
Author(s): Fedora glibc team <glibc@lists.fedoraproject.org>
Origin: PATCH
Bug-RHEL: #741105, #767146
Upstream status: not-needed
This change is designed to work around running ld.so on a debuginfo
file. This is the wrong fix for this problem and should be dropped.
The correct solution is to mark debuginfo files as new types of
ELF files.
