Okay, so the AX_BOOST_BASE() macro doesn't work properly in cross-compiling

One way to solve this is to provide the BOOST_* values as configure
arguments, such as:

    ./configure --host=i686-pc-mingw32 BOOST_CPPFLAGS="..." BOOST_LDFLAGS="..."

Note that there are some more ways to solve this issue. Maybe another
Boost user on this list will propose a better way that doesn't require
additional arguments.
