Wandboard-quad hangs during port install

[Ulrich Grey]

Hello,

I am running this snapshot image (11.0-CURRENT FreeBSD 11.0-CURRENT #0 r284969: Wed Jul
1) on a wandboard-quad.

During installation of security/gcr the system hangs. Breaking to debugger shows this
(see attached file):

root at wqtest:/usr/local/DEVEL/ports/x11-toolkits/gtk30 # KDB: enter: Break to debugger
