commit r12-10280-g413b91e1faacf5fd5d5ffe099898f46750c7f601
Author: Jonathan Wakely <jwak...@redhat.com>

libstdc++: Move __glibcxx_assert_fail to its own file
This avoids a dependency on the other symbols in src/c++11/debug.o when
linking statically to libstdc++.a without using -Wl,--gc-sections.
libstdc++-v3/ChangeLog:
* src/c++11/Makefile.am: Add new file.
* src/c++11/Makefile.in: Regenerate.
* src/c++11/debug.cc (__glibcxx_assert_fail): Move to ...
* src/c++11/assert_fail.cc: New file.
(cherry picked from commit c7db9000fa7caceadb4e72dcc6226abebf7a6239)
