Bug#745372: When build apt (1.0.1) with gcc-4.9, it cannot start with libstdc++6 (4.8)

[Yunqiang Su <wzssyqa@gmail.com>]

Package: gcc-4.9
Version: 4.9-20140411-2

I built apt with gcc-4.9, then install it on a system with libstdc++6
(4.8), it failed to start:

apt-get: /usr/lib/mips64el-linux-gnuabi64/libstdc++.so.6: version
`GLIBCXX_3.4.20' not found (required by apt-get)
apt-get: /usr/lib/mips64el-linux-gnuabi64/libstdc++.so.6: version
`GLIBCXX_3.4.20' not found (required by
/usr/lib/mips64el-linux-gnuabi64/libapt-pkg.so.4.12)
apt-get: /usr/lib/mips64el-linux-gnuabi64/libstdc++.so.6: version
`GLIBCXX_3.4.20' not found (required by
/usr/lib/mips64el-linux-gnuabi64/libapt-private.so.0.0)


While apt doesn't depend on libstdc++6 with version.
It must be something wrong.

After install libstdc++6 (4.9), all of them works well now.
