We hashed this out a bit off-list, to avoid filling the audit trail with more
bad guessing of mine.

Anyway, turned out the exposer for this issue was the passing of a number of
configure command lines that conflicted:
  --enable-shared --disable-static --enable-shared=libstdc++ --enable-static

I told Gabor to rebuild with
  --disable-shared --enable-static --enable-shared=libstdc++-v3

intending to create a shared C++ library but everything else static.  The build
finished successfully, but without creating a shared C++ library.  I now
checked the libstdc++-v3/configure code, and sorry to say so, but I was wrong,
libstdc++-v3/configure defines $PACKAGE as "libstdc++", so that the right set
of args would have been
    --disable-shared --enable-static --enable-shared=libstdc++

instead.  Gabor, can I ask you to retry with these argumenst one more time?  If
that fails to produce a shared C++ library, then please open a new PR "building
only some GCC libraries shared" against component bootstrap, point to this PR,
Cc: me, and attach the build log, gzip'ed.  Thank you.

I'm closing this PR as invalid.  (I don't want to retitle it because the old
name should remain searchable.)
