I believe this comes from the libcurl and specifically the ntlm_wb support
which is often enabled in system and package manager provided installations.
There isn't really a fix here apart from requiring a libcurl not compiled with
ntlm_wb support, or adding an exception to the exit() check in the Makefile.

Bringing this up with other curl developers to see if it could be fixed we
instead decided to deprecate the whole module as it's quirky and not used much.
This won't help with existing installations but at least it will be deprecated
and removed by the time v17 ships, so gating on a version shipped after its
removal will avoid it.

There is no corresponding check in the Meson build, which seems like a TODO.
