[PATCH] sim: erc32: fix linking against local readline on modern (ncurses) systems

[Mike Frysinger]

i've committed this initial fix based on Joel's feedback:

2011-12-31  Mike Frysinger  <vapier@gentoo.org>

    * configure.ac: Change AC_CHECK_LIB to AC_SEARCH_LIBS to match
    the code in gdb's configure.ac with $TERMCAP.
    * configure: Regenerated.
