Bug 31646: Update abicheck to require GLIBCXX_3.4.25

This is also fixing bug 31380.
parent 3b899b76
/*
* Bug 25485: Browser/TorBrowser/Tor/libstdc++.so.6: version `CXXABI_1.3.11' not found
* This program is borrowed from
* https://en.cppreference.com/w/cpp/error/uncaught_exception and is useful in
* determining the latest C++ ABI. Specifically this program requires
* `GLIBCXX_3.4.22` which we use to compare the version of the installed
* libstdc++.so.6 and the bundled version. If the program executes
* successfully, that means we should use the system version of libstdc++.so.6
* and if not, that means we should use the bundled version.
* Bug 31646: Update abicheck to require newer libstdc++.so.6
* This program is useful in determining if the libstdc++.so.6 installed
* on the system is recent enough. Specifically this program requires
* `GLIBCXX_3.4.25` which should be provided by libstdc++.so.6 from
* gcc >= 8.0.0. If the program executes successfully, that means we
* should use the system version of libstdc++.so.6 and if not, that means
* we should use the bundled version.
*
* We use std::random_device::entropy() in order to require GLIBCXX_3.4.25:
* https://github.com/gcc-mirror/gcc/blob/gcc-8_3_0-release/libstdc%2B%2B-v3/config/abi/pre/gnu.ver#L1978
