you update your ports collection, before attempting any port upgrades.

  AFFECTS: users of Qt 5 in presence of binutils
  AUTHOR: amdmi3@FreeBSD.org

  gold linker from binutils 2.28 may produce duplicate library
  symbols, which makes shared libraries created with it not usable
  with conventional ld linker.

  This affects Qt, as qt5-qmake will detect gold and use it to build
  Qt libraries. Broken libQt5Core will be produced and ports which
  depend on it will then fail to link with the following errors:

    ...lib/libQt5Core.so:(.dynamic+0x27ac8): multiple definition of `__bss_start at Qt_5'
    ...lib/libQt5Core.so:(.dynamic+0x27ac8): first defined here
    ...lib/libQt5Core.so:(.dynamic+0x27ac8): multiple definition of `_edata at Qt_5'
    ...lib/libQt5Core.so:(.dynamic+0x27ac8): first defined here
    ...lib/libQt5Core.so:(.dynamic+0x2b2d0): multiple definition of `_end at Qt_5'

  Qt5 was fixed to ignore gold. If you see these errors, you
  need to rebuild qt5-qmake, then all qt5-* ports.
