libstdc++: Remove symbols for new std::call_once implementation [PR 99341]
This removes the new symbols added for the new futex-based
std::call_once implementation. These symbols were new on trunk, so not
in any released version. However, they are already present in some
beta distro releases (Fedora Linux 34) and in Fedora Linux rawhide. This
change can be locally reverted by distros that need to keep the symbols
present until affected packages have been rebuilt.

crt files and statically linked libgcc objects cause false positives
in annobin coverage, so we add the assembler flag to generate notes
for them.

The patch also adds notes to libgcc_s.so, but this is harmless because
these notes only confer that there is no other annobin markup.

%description -n %{cross}-gcc-common
Documentation, manual pages and translation files for cross-build GNU C
compiler.

This is the common part of a set of cross-build GNU C compiler packages for
building kernels for other architectures. No support for cross-building
user space programs is currently supplied as that would massively multiply the
number of packages.
