I have (on openSuse 13.2)

Name        : pkg-config
Version     : 0.28
Release     : 7.1.2
Architecture: x86_64
Source RPM  : pkg-config-0.28-7.1.2.src.rpm
Build Date  : Thu 25 Sep 2014 16:37:13 AEST

The version I built from a git clone behaves correctly

> ./pkg-config --static --libs QtCore
-lQtCore -lpthread -lz -lm -ldl -lgthread-2.0 -pthread -lglib-2.0 -lrt
