Description
I'm trying to build Qt on Gentoo x32 ABI (x86_64 with 32bit pointers), and I run into following problem:
/var/tmp/portage/dev-qt/qtbase-6.6.1-r4/work/qtbase-everywhere-src-6.6.1_build/include/QtCore/../../../qtbase-everywhere-src-6.6.1/src/corelib/thread/qthread.h: Assembler messages:

Fix (patch) is attached to this ticket.
Comment: pthread_t on x32 ABI is 32bit, therefore it should not be 'movq' but rather 'mov'. I made simple program to compare output of asm command and pthread_self(), and they provide identical output.
