Fixed link problem when compiling without uca

cmd-line-utils/readline/config_readline.h:
  Add back defines needed for linux to get rid of compiler warnings, but hide them for now until we have a solution for compile failure on MacOSX
strings/ctype-uca.c:
  Always define UCA contraction functions used by ctype-mb.c
