    Fixes #17525.

    Debian 8 (Jessie, oldoldstable) has:

    Debian 9 (Stretch, Oldstable) has:

    Ubuntu 16.04.4 (Xenial, oldest supported Ubuntu) has:

    Taking the minimum of these as our target.

    According to GNU ABI document (http://gcc.gnu.org/onlinedocs/libstdc++/manual/abi.html) this corresponds to:

    • GCC 4.9.2: GCC_4.8.0
    • (glibc) GLIBC_2_19

    This also contains a (long needed) commit to disallow dynamic linking to stdc++, as our releases statically link against that.

    It might be possible to remove some fallbacks from src/compat/glibc_compat.cpp, too. But I’ll wait for the version decision first.

  2. build: Disallow dynamic linking against c++ library 
    Ever since statically linking Qt, we've been linking the C++ library
statically too (-static-libstdc++). Take this into
account in the symbol checker.

    Could also do Debian 8 (Jessie, oldoldstable):

    Which would be:

    • GCC 4.9.2: GCC_4.8.0
    • (glibc) GLIBC_2_19

    This would still fix #17525, which requires at least 2.16.

  10. build: Bump minimum versions in symbol checker 
    Debian 8 (Jessie) has:

- g++ version 4.9.2 (https://packages.debian.org/search?suite=jessie&arch=any&searchon=names&keywords=g%2B%2B)
- libc version 2.19 (https://packages.debian.org/search?suite=jessie&arch=any&searchon=names&keywords=libc6)

Ubuntu 16.04.4 (Xenial) has:

- g++ version 5.3.1 (https://packages.ubuntu.com/search?keywords=g%2B%2B&searchon=names&suite=xenial&section=all)
- libc version 2.23.0 (https://packages.ubuntu.com/search?keywords=libc6&searchon=names&suite=xenial&section=all)

Taking the minimum of these as our target.

According to GNU ABI document (http://gcc.gnu.org/onlinedocs/libstdc++/manual/abi.html) this corresponds to:

- GCC 4.9.2: GCC_4.8.0
- (glibc)    GLIBC_2_19

    I have backed this down to 2.19 (Debian Stretch/Oldoldstable). I see no reason to push for anything higher. Should be uncontroversial now.

    Feel free to pick this up, I don’t feel like bothering with the eternal pit of misery that is distributing binaries for Linux anymore.
