  Sorry for this issue. My bad as I had access to this system
https://cfarm.tetaneutral.net/news/41#

  When reading your email, I mostly guessed what could be wrong.

  I just tested in gcc104, and you can get it to mostly work if building as:

$ ./configure --enable-assertions CFLAGS="-D__OpenBSD__=1"
$ make CFLAGS="-D__OpenBSD__=1"

  Fixing the above is trivial.
 The major problem should be a different ABI for variadic functions.

  It should also be mostly trivial. It appears to use a very simple
va_list as described at
https://developer.apple.com/documentation/xcode/writing-arm64-code-for-apple-platforms

  Doing some initial work/research with a very simple example I get:

gcc104:check pcpa$ lldb .libs/lightning
...
(lldb) r add.tst
error: process exited with status -1 (this is a non-interactive debug
session, cannot get permission to debug processes.)

apparently need some special procedures if running in a ssh connection.

  But hopefully  it will not be required to be able to use a debugger as
long as my guesses are right :), and fixing the lldb issue probably
needs sudo privilege.

  I believe I will not be able to work on it early today. But hopefully
by tomorrow I will have a patch.

  Sorry for not having properly tested it for the Lightning 2.1.4 release.
