Thanks a lot, but this needs more explanation. Why is libatomic_ops not

Currently I don't have a clear answer. I've tested building external
libatomic-ops with configuration keys I've taken from the build of internal
one. I'll look into them more.
Also I think I'll try to downgrade lib to version used in mono(7.6.10 ->
7.4.2)
I suspect it currently doesn't build mono on the whole ARMv5 but I've
failed to test it.
