The answer to this question may be in the following lines of bootstrap.sh.  If
ICU is not found in any of those "common" locations, then bjam is called
without any -sICU_PATH option and it may be that it finds the correct location
automatically (by using passed LDFLAGS or something).

I started using Boost with ICU very recently, so I can't tell from my own
experience if this is what happens indeed.
