Message ID 2b971b558fa20e875348aa2213e0ad385f72d20f.1449400403.git.yann.morin.1998@free.fr

The gawk debugger can optionally use readline for user input during
the debugging session (for the usual autocompletion and stuff).

Enable readline support when the readline package is enabled; let
./configure automatically find it. Forcibly disable readline support
when the readline package is disabled.
