Two ports, devel/rubygem-glib2 and graphics/rubygem-cairo, have been
broken on armv7 for a long time. Recently, pkubaj fixed a problem with
Ruby's coroutine code on ppc64* (see 3bb0a9335) affecting the very same
ports. This naturally raises the question if the armv7 problems are
related.
Turns out that due to an oversight, we use the generic ucontext.h-based
coroutine code on armv7. Switching to the assembly-based code fixes
the ports! Further digging suggests that there may be a problem in the
freebsd32 support for these calls on aarch64 causing the observed
issues. We will investigate those separately.
