Ubuntu 22.04: can't install the built library, and autotools config uses obsolete macros

[cxw42]

(Opening on behalf of a friend of mine)

Thanks for this project, which is very useful!

• The generated Makefile doesn't seem to install the libs.
• Running ./autogen.sh on an Ubuntu 22.04 (autoconf 2.71) produces a number of warnings

This seems to be similar to https://gitlab.com/openconnect/openconnect/-/issues/413.

I see from the 2.71 announcement that there are some compat breaks with 2.69 and older, and this package currently targets >=2.61. See also the autoconf changelog.
