Title: boost: fix building with icu by using with-c++11

boost needs the `--with-c++11` option if it's going to build
with icu4c-50.1. This is partially due to a change in icu4c,
as the previous version compiled into boost without error.
The current icu4c-50.1 does pass `make check`.

- Enable the c++11 if when the user throws `--with-icu`.

Fixes #16144
