I've confirmed there is no asm, and the file in question *was* built
with -fPIC:

g++ -c -m64 -pipe -I/usr/include/mysql -fno-exceptions -O2 -g -pipe -Wall \
-Wp,-D_FORTIFY_SOURCE=2 -fstack-protector --param=ssp-buffer-size=4 -m64 \
-mtune=generic -fvisibility=hidden -fvisibility-inlines-hidden -Wall -W \
-D_REENTRANT -fPIC  -DQT_SHARED -DQT_BUILD_CORE_LIB -DQT_NO_CAST_TO_ASCII \
-DQT3_SUPPORT -DQT_MOC_COMPAT -DQT_NO_DEBUG -D_LARGEFILE64_SOURCE \
-D_LARGEFILE_SOURCE -I../../mkspecs/linux-g++-64 -I. -I../../include \
-I../../include/QtCore -Iglobal -I.moc/release-shared -I. \
-o .obj/release-shared/qthread_unix.o thread/qthread_unix.cpp
