[Buildroot] [PATCH 4/4] package/sqlite: add optional support for libedit

[Bernd Kuhls]

Only one library is used for command-line editing by sqlite, therefore
create a choice option between current readline support and libedit.

The default of the choice option is readline in order to not change
current behaviour in buildroot. Please note that sqlite first checks
for libedit and, if found, ignores readline, see configure.ac,
lines 50+:

  if test x"$LIBS" != "x"; then
     AC_DEFINE([HAVE_EDITLINE],1,Define to use BSD editline)
  else
    unset ac_cv_search_readline
  fi
