The current FreeBSD/ARM __clear_cache() implementation does nothing #if
__i386__ || __x86_64__ #else abort();
cognet@ advises this is an issue for anything !Apple that is using the
libcompiler_rt provided by Clang on ARM, and requires upstreaming.
This is the root cause of abort() on import for the ctypes module in
Python, as they bundle libffi. [1]
This change patches the bundled libffi library in all Python ports, even
though it is a NOOP for the ports that use devel/libffi. These ports,
currently python31, will get the fix via ports/184517
A huge shout out to cognet@ who helped diagnose the issue and created
the patch to address it. Thank you!
