libosmocore/osmocombb build error

[Job]

Hi,

While further investigating the autoconf aspects of libosmcocore I ran
into some counter intuitive use of the conditional options. It seems
they are not implemented in the expected way.

I guess the intention of --disable-feature is that you can also say
--enable-feature (even if this is the default) or that
--enable-feature=no should work as this is a standard behavior of
configure. In the current use of the AC_ARG_ENABLE macro this fails.
According to
http://www.flameeyes.eu/autotools-mythbuster/autoconf/arguments.html
the  action-if-present and  action-if-not-present should not be used in
this way. Shall I modify this in a separate patch?

What about
--disable-vty
--enable-panic-infloop
--disable-shared
--disable-talloc

That are now also part of the build-target configure options?

Best regards,
