* build: fix wrongly linking against libreadline in all applicationsThomas Haller2014-11-261-0/+2
| | | | | | | | | | Every Makefile in the subtrees would include -lreadline as part of LIBS, hence every application would link against the library. This was broken since we added 'm4/ax_lib_readline.m4'. Fixes: 29297f8531e24d4df616c5c3acace9e23a695a02

* build: check harder for readlineDan Williams2014-06-271-0/+106
Not all distros build their readline linked with a termcap library, since apps are (apparently) supposed to choose one for themselves and explicitly link to it when using readline. So add some checks to figure out whether readline is already linked, and if not, prefer ncurses since we use that for nmtui already. ax_lib_readline based off: http://www.gnu.org/software/autoconf-archive/ax_lib_readline.html
