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

- Subject: [PATCH] sim: erc32: fix linking against local readline on modern (ncurses) systems
The current erc32 configure script only searches for -ltermcap to provide
any termcap funcs (which readlines needs). When building against a local
readline (which is static), we hit link failures like so:
gcc ...-I/-D flags... -o sis \
sis.o exec.o erc32.o func.o help.o float.o \
../../bfd/libbfd.a ../../opcodes/libopcodes.a \
../../libiberty/libiberty.a -lz -lnsl \
../../readline/libreadline.a -lm
../../readline/libreadline.a(display.o): In function 'cr':
.../readline/display.c:2486: undefined reference to 'tputs'
collect2: ld returned 1 exit status
make[2]: *** [sis] Error 1
Use AC_SEARCH_LIBS to check for ncurses/curses (which should be the
modern equivalent on most systems for libtermcap).

* configure.ac: Change AC_CHECK_LIB to AC_SEARCH_LIBS, and add
ncurses/curses to the library search list.
* configure: Regenerated.
