Actually the transition to -funit-at-a-time is not seamless for libstdc++.
I first re-compiled libstdc++ by using
make CXXFLAGS="-g -O2 -funit-at-a-time" all
after removing the build directory. Then, I added -funit-at-a-time to
scripts/testsuite_flags.h so that
--cxxflags)
CXXFLAGS_save="-g -O2 -funit-at-a-time"
Then, I ran make-check in the libstdc++ build directory. I got seven new failures:

These all exhibited the same pathology: missing definitions for virtual dtors.
