[Bug libstdc++/35942] Self Reference In Dynamic Linked Library builds for building Cross-Compiler

Well, I answered my own question, sort of...

In my /usr/bin/libtool, in the CXX tag section, I have

postdeps="-lstdc++ -lm -lgcc_s -lc -lgcc_s"

so voila, that's where it comes from, probably.

So this issue can now be reduced to the following:

Native builds and cross-compiles of libstdc++.so override this postdeps and
zero it out.  However, using a cross-compiler to generate host=target native
compiler with build!=host leaves it pulled in, being responsible, I believe,
for this bug.  Whether that's a libtool bug or a libstdc++ configure bug remain
unanswered...  Maybe this is a new wrinkle that newish versions of libtool have
and perhaps has not needed to be dealt with before.
