This patch fixes the cause of the following build output during a
non-bootstrap build:
make[2]: Entering directory
`/home/patrick/code/gcc-build/x86_64-unknown-linux-gnu/libgcc'
# If this is the top-level multilib, build all the other
# multilibs.
# Early copyback; see "all" above for the rationale. The
# early copy is necessary so that the gcc -B options find
# the right startup files when linking shared libgcc.

The vtv_*.o files are only built when vtable verification is enabled
(--enable-vtable-verify) and are otherwise nonexistent. Therefore
these object files should only be added to $(EXTRA_PARTS)
when vtable verification is enabled.

* config.host (extra_parts): Don't include vtv_*.o objects unless
vtable verification is enabled.
