[HarfBuzz] Detecting ICU/FreeType without pkg-config?

Dear Jiang,

This is what we do in grcompiler. I don't know if it is any good, but it seems to work.

AC_CHECK_LIB(sicuuc, u_charType_3_6)
AC_CHECK_LIB(sicuuc, u_charType_3_8)
AC_CHECK_LIB(sicuuc, u_charType_3_9)
AC_CHECK_LIB(sicuuc, u_charType_4_0)

# Checks for header files.
# need to check for icu .h files as in unicode/uchar.h
AC_CHECK_HEADER(unicode/uchar.h,,)

Yours,
Martin
