Mark Millard <markmi at dsl-only.net> has reassigned Bugzilla Automation
<bugzilla at FreeBSD.org>'s request for maintainer-feedback to kde at FreeBSD.org:
Bug 207099: lang/qt5-qml: for armv7 (rpi2), error: "The cacheFlush support is
missing on this platform." (stops the build)

--- Description ---
[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-CURRENT has SCTLR bit[1]==1 for such contexts.]

When I attempt portinstall/portmaster builds for lang/qt5-qml I get the
following.

which stops the overall build.

Stop reading the description here if you do not care about supporting details
at this point.
