Complete build log

Complete build log is attached.
To summarize:

System is stable/11 amd64 at r316491, thus the system compiler is FreeBSD's
clang 4.0.0. Ports tree is at r437806.

x11-toolkits/qt5-widgets complains about duplicate symbols in libQt5Core.so:

/usr/ports/workdirs/usr/ports/x11-toolkits/qt5-widgets/work/qtbase-opensource-s
rc-5.7.1/lib/libQt5Core.so:(.dynamic+0x27ad8):

rc-5.7.1/lib/libQt5Core.so:(.dynamic+0x2b2d0):
multiple definition of `_end at Qt_5'

Note, the linker is referring to a library from within the work directory, not
the library installed in /usr/local/lib/qt5 by devel/qt5-core. Maybe that's the
real problem.
