[Buildroot] [PATCH 01/21] libftdi: C++ bindings need boost

[Thomas Petazzoni]

According to libftdi configure.in:

"""
dnl libftdi C++ wrapper. Needs boost.
[...]
        if test "x$HAVE_BOOST" != "xyes"; then
            AC_MSG_ERROR(Sorry, we need the boost library for the C++ wrapper)
        fi
"""

And indeed, if you enable BR2_PACKAGE_LIBTFDI_CPP but don't have Boost
enabled, the libfdipp library is not built. To fix this, this commit
changes BR2_PACKAGE_LIBTFDI_CPP to select Boost.
