Only the C language is fully supported, and - the error tests are skipped.

Build time is reduced ~20% when tools are - disabled, 35% when tests are disabled, 45% when both are disabled. - Reenabling them after the initial build requires running configure - again with the option(s) enabled. - - (LRK - 2019/06/12, HDFFV-9976) - - - Change tools test that test the error stack - - There are some use cases which can cause the error stack of tools to be - different then the expected output.
