Re: libobjc2 still failing tests

Actually both armv7-a (vfpv3-d16 no neon, and softfp) and yes AArch64 

armv7-a is working great for us on android with current stock Google NDK which 
is using clang-8...  but we seem to be experiencing an ivar alignment or offset 
bug on arm64-v8a.

We had to rework SmallObjectClasses assembly reference because android will not 
load any library that has any text relocations in a library.  (I believe we can 
probably get around that by using the GOT to get to SmallObjectClassess but we 
have just removed for now).  

But ya, Ideally I want to run the test suite on an actual android device to 
figure out this ivar issue on AArch64.  So, hmmmmmm, I guess I'll try and think 
of some way to get the test executable main()s onto an actual android device 
for testing...
