Subject: avoid "unused return value" gcc warnings
Patch-mainline: No

Avoid gcc warnings about unused return values of some functions.
These warnings are considered fatal by BuildService checks so
that we must avoid them in SLE packages even if only by
assigning the return value to a variable which we never use.
