The error in the log is:

g++ -Wl,-Bsymbolic-functions -Wl,-z,relro -Wl,--as-needed -Wl,-O1 -fuse-ld=gold -o ubuntu-ui-toolkit-launcher .obj/launcher.o .obj/MouseTouchAdaptor.o -L/usr/X11R6/lib64 -lQt5Quick -lQt5Gui -lQt5Qml -lQt5Network -lQt5Test -lQt5Core -lGL -lpthread 
/usr/bin/ld.gold: --push-state: unknown option
/usr/bin/ld.gold: use the --help option for usage information
collect2: error: ld returned 1 exit status

But --push-state only ever appears in the error message; it does not appear
in the g++ commandline that the build system claims to be invoking.  Has
anyone tracked down the origin of this?  I do see '--push-state' in the
output of 'strings /usr/bin/g++', so it's certainly possible that g++ itself
is adding it to the commandline when invoking ld.  If so this is definitely
a gcc bug, passing extra arguments to ld regardless of which ld is being
called, and it doesn't matter what libraries are being passed.

  TJ- on #ubuntu-devel suggested:
  < TJ-> Mirv: bzoltan: the issue could be in qtbase-opensource-src-5.4.2+dfsg (qmake) which does "mkspecs/common/gcc-base-unix.conf:19:QMAKE_LFLAGS_USE_GOLD   = -fuse-ld=gold" irrespective of libraries being linked.

  Ideas for a proper fix welcome.
