The best method for cross-compiling ICU is to create two copies of the source directory, side-by-side. Name one directory icu-host and compile it first for the host build machine. After that finishes, create a symbolic link to icu-host/bin and icu-host/lib inside the target source directory. Apply the attached patch to the target source directory and build it. * icu-cross-compile.patch: Cross compiling patch for ICU 3.8
