- Adjust license tags to follow SPDX conventions.

- Properly use FULLVER in cppbuiltin.c. [bnc#742747]

- Use proper groups for the documentation packages. [bnc#732685]

- When building libffi use make stage1-bubble to build the
C compiler, not make all-gcc.
------------------------------------------------------------------
- run all-gcc first, otherwise /xgcc might not exist, so
make all-target-libffi fails to configure (depending on race
conditions)
- apply changes from obs-service-format_spec_file to gcc.spec.in
to make diffing somehow sane:
* Release: is now always 0
* only one Buildrequires per tag
* Autoreqprov: on is default since ages and unneeded
* Summary: is the first line after %package
* Group comes before other tags
