va: fix configure check for --version-script with --no-undefined-version

In the upcoming LLD 17 (and previously in LLD 16.0.0, but reverted in 16.0.1),
--no-undefined-version is becoming the default behavior. This causes the
configure check for --version-scripts support to fail due to the symbols
in the version script not being defined, which will cause the version
script to not be used, and the build will fail due to
--no-undefined-version. This commit adds '-Wl,--undefined-version' to
the args of the configure check.
