After merging the changeset for JDK-8186476, the linux-zero build fails with:

* For target hotspot_variant-zero_libjvm_objs_bitMap.o:

This is a result of the use of STATIC_CAST instead of STATIC_ASSERT in the changes for 8186476.

Additionally, for linux-sparc, "template<>" is missing in one instance:
