That's a bug in AC_CHECK_CURSES_COMPILE, and should be reported to
whoever wrote that macro.  The autoconf manual says that LDFLAGS is for
-L options, while LIBS is for -l options.

and this is a blatant case of using the wrong env-var for library
probing.  s/LDFLAGS/LIBS/ on these lines, before running autoreconf, and
that should fix it without you manually having to pass LIBS= at the
configure command line.
