archivers/lzo2 on arm cortex-a7 (rpi2b) : ./lzotest/lzotest -mlzo -n2 -q ./COPYING gets "Signal 10" and stops the build

[Mark Millard]

[Context basics: projects/clang380-import -r295351 for buildworld/buildkernel that targeted an rpi2 (armv7-a/cortex-a7). This context requires strict alignment: FreeBSD 11.0-CURRNET has SCTLR bit[1]==1 for such contexts.]

When I attempt portinstall/portmaster builds for an arm rpi2 context that depend on lzo2 I get the following.

I have submitted Bug 207096 for this misalignment problem. It has some more supporting detail in its description.
