description:
earmv7hf gcc also miscompiles ocpnDC::DrawRounderRectangle now
(or maybe opencpn 4.8.0 didn't use it).
Apply the same workaround as ocpnDC::DrawEllipse.

+For some reason ocpnDC::DrawEllipse and ocpnDC::DrawRounderRectangle
+and is miscompiled on NetBSD 8.0_BETA and gcc 6.4 from HEAD earmv7hf:
 for the tail call to dc->DrawEllipse() the compiler emits a bx instruction,
 but forgets to load the address of the function in the register.
 The memory barrier works around this problem by avoiding the tail-call
 optimisation.
 Other similar functions in this file are properly compiled ...
+I suspect it's related to the vfp register use in these functions.
