[GIT] kbuild fixes

[Sam Ravnborg <sam@ravnborg.org>]

Hi Linus.

- various .gitignore updates
- disabling of -Wformat-security
  We looked at it and 'fixing' the warnings was not pleasant
- fixes/improvements for the newly introduced macros in asm-generic/vmlinux.lds.h

Nothing earth-shaking..
And it has been in -next for a few days with no issues.

I am heading for a two week vacation in Sweden and will
be offline in that period.
Enjoy the kernel hacking while I enjoy my vacation :-) 

	Sam
