With some build environments (e.g. clang, see #1613) linking fails with
unresolved references. This is caused by the inclusion of 'unused code'
which is usually discarded by the linker. The 'unused code' contains
references to functions that have not been 'stubbed' out. The failure
can be seen by removing 'LDFLAGS += -Wl,--gc-sections' in
spdk.unittest.mk
Resolved by adding stubs for missing references. These are never called
so return an arbtrary default value.
