Comment (by sukhbir):

 I wonder why I can't seem to reproduce this. I tested this on Mint 17.3,
 updating from 7.5.6 as well as doing a clean install. Even running
 `abicheck` manually seems to confirm the intended behaviour:

 {{{
 ./Browser/abicheck: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version
 `GLIBCXX_3.4.22' not found (required by ./Browser/abicheck)
 ./Browser/abicheck: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version
 `GLIBCXX_3.4.21' not found (required by ./Browser/abicheck)
 }}}

 which means that for Mint 17.3, we use our bundled `libstdc++` since
 `abicheck` returns a non-zero value. (Same is the case for Ubuntu 14.04).

 But that's expected as well for the same reason and goes away when you
 point it to the right version of `libstdc++`.

 So yes, judging by the error and the fix, it would seem that `abicheck` is
 not working as intended. I have asked for the output of that on the blog
 and we will track the progress here.
