Bug#364231: exception catching broken on HPPA

$ ldd a.out
        libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x40575000)
        libm.so.6 => /lib/libm.so.6 (0x4046e000)
        libgcc_s.so.2 => /lib/libgcc_s.so.2 (0x40068000)
        libc.so.6 => /lib/libc.so.6 (0x4074b000)
        libgcc_s.so.4 => /lib/libgcc_s.so.4 (0x40015000)
        /lib/ld.so.1 (0x400e1000)

We end up with both libgcc_s.so.2 and libgcc_s.so.4 linked.  Is there
a solution other than making gcc-4.1/g++-4.1 the default and
rebuilding the libstdc++6 dependent packages with binary NMU's?
