SIGBUS on OpenBSD

CLN at 5af9d19

OS: OpenBSD 7.4
Arch: SPARC64
Network: signet
Compiler: GCC 8.4

CLN crashes soon after starting. I realize sparc64 is ancient but these logs may be useful?

Oh should I refile in the ccan repo instead?

@grubles I suspect you need something like ElementsProject/libwally-core@745bc55 applied to the cln ccan config.
