Hi!
We currently bootstrap both libsanitizer and libvtv, the former
just in case somebody decides to --with-build-config=bootstrap-asan
(or --with-build-config=bootstrap-ubsan), the latter if somebody decides
to --enable-vtable-verify.
This patch changes it so that we only bootstrap libsanitizer if
bootstrap-asan or bootstrap-ubsan is in BOOT_CONFIG, and only bootstrap
libvtv if --enable-vtable-verify.
Bootstrapped/regtested on x86_64-linux and i686-linux, on x86_64 it
saved a few minutes of build time, neither libsanitizer nor libvtv
has been bootstrapped, only built in stage3.
Currently also bootstrapping on i686-linux with
--enable-vtable-verify --with-build-config=bootstrap-asan
but already got into stage2 and verified that both libsanitizer and libvtv
are being bootstrapped in that case.
Ok for trunk?

* configure.ac: Move BUILD_CONFIG set up earlier. Add
--enable-vtable-verify option parsing. Don't add
target-libsanitizer to bootstrap_target_libs unless
--with-build-config=bootstrap-asan or
--with-build-config=bootstrap-ubsan. Don't add target-libvtv
to bootstrap_target_libs unless --enable-vtable-verify.
* configure: Regenerated.
