I'm not so worried about the number of tests, but about the complexity
of the code. You are turning a simple 10-line check in a 90-line
monster, that's really too much for such an obscure feature that
pretty much nobody uses. I'd suggest something along these lines:

  for i in ${ICU_LIB_DIR-/usr/lib}/libicu \
     LIBS="${i}uc.a ${i}data.a $LIBS"
     AC_TRY_LINK etc.

You can add /usr/local/lib to the mix if you like, but I don't think
that's really necessary.
