EH fails if libstdc++.so built with -ffunction-sections

[Chip Salzenberg <chip at valinux dot com>]

I have a program that dumps core when it throws an exception.  The
program is dynamically linked to a v3 libstdc++.so.

The same program, staically linked, works fine.

I arranged to compile libstdc++.so with -ffunction-sections but not
-fdata-sections, The program still failed that shared object.  So
apparently -ffunction-sections kills EH in shared libraries.  I would
test without it, but -ffunction-sections is a standard part of the
build process these days.
