Пакет libstdc++-devel: Изменения

- Support Fortran conditionally.

- Update to lcc1.25.

- Add gcov support.

- Add gcc compatibility provides for fine granularity deps control.

- Add missed libquadmath-devel-static virtual package.

- Update for lcc1.24.
- Provide more gcc-compatible packages.
- Add optional gcov support (disabled for now).

- Provide $name-%gcc_compat_branch compatibility symlinks. Some applications
  need this. This way we are more compatible with sisyphus.

- Enable libgfortran-devel{-static} generation in order to provide dummy
  packages for demanding clients.

- Add Provides: for compatible gcc subpackages
  since some useful packages still BR: gcc5-c++.
- Drop Conflicts: dummy-gcc-c++ (obsolete).

- Add libgomp{,-devel} dependency packages.

- Introduced FORTRAN knob (disabled for 1.23 bootstrap).

- Exceptional package names for libstdc++.

- Exceptional version for libatomic5-devel-static.

- Fixed installation (with rpm --excludedocs option) of subpackages containing
  symlinks on gcc manpages (ALT#34996).

- Fortran enabled.

- Restored: gcc-{ar,nm,ranlib} (expected by, e.g., systemd build).

- lcc's Epoch set in Obsoletes not to interfere with the new Provides
  or any future pkgs.

- Switched to lcc-1.21. (For e2k, lcc is the only available native compiler.)

- (.spec) Made possible to disable noarch subpkgs.
- More specific Group for gcc-c++. (ALT#34901)
- Filled URL. (ALT#34624)

- aarch64: packaged liblsan-devel-static and libtsan-devel-static.
