Fix Windows ICU build by making sure the cross compiled ICU exists before building boost.

Add some additional logging during ICU configuration and build process.

Resolve ICU on windows link issues.

Add /tmp/icu_install (cross-compile staging build) to the travis
directory cache for future windows builds.
