Hello.

Following patch adds a clang-format config file that should respect the GNU 
coding standards.
As the file is not part of build process, I hope the patch can be applied even

we've just skipped to stage3? The patch adds a hunk to Makefile which can 
create symlink
to the root directory of the GCC compiler. The clang-format automatically loads 
style from
the configuration file.

clang-format (version 3.8) provides rich variety of configuration options that 
can
ensure the GNU coding style.

Limitations:
+ placement of opening brace of an initializer can't be requested
+ sometimes, '(' is the trailing symbol at the end of a line, which can look 
weird

As we've been continuously converting our source base to C++, the clang-format 
should
provide better results than a collection of regular expressions 
(check_GNU_style.sh).

As a reference file I attach gcc/tree-ssa-uninit.c file.
Feel free to comment the suggested configuration file.
This is fine. Given that gnu-indent seems to muck up C++ badly in my experience, clang-format may be a better long term solution. I'd really like to get to a point one day where formatting is a commit hook so that things are always kept properly formatted.
