PR libstdc++/91067 fix missing exports for filesystem iterators
The copy assignment operator for recursive_directory_iterator was not exported despite being needed. The __shared_ptr default constructors are not needed when compiling with GCC but Clang requires them for -O1. PR libstdc++/91067 * acinclude.m4 (libtool_VERSION): Bump to 6:27:0. * configure: Regenerate. * config/abi/pre/gnu.ver (GLIBCXX_3.4.27): Add new version. Export missing symbols. * testsuite/27_io/filesystem/iterators/91067.cc: New test. * testsuite/util/testsuite_abi.cc: Add new symbol version. From-SVN: r273023
