The current usage mode here is:

--with-clib-autodetect=0 --with-cxxlib-autodetect=0 --with-fortranlib-autodetect=0 LIBS=-lstdc++

In this mode - I don't think configure should be gussing - and let the
user provide the appropriate compatibility library list.

If any fixes - they should go for usage:
--with-clib-autodetect=1 --with-cxxlib-autodetect=1 --with-fortranlib-autodetect=1
