Remove "#ifdef linux" from include/linux/a.out.h

[Alexander Ivchenko]

Hi,

GCC fixincludes always change that header to comply with C standard.
Here is the comment from fixincludes code:
/* Fix for machine name #ifdefs that are not in the namespace reserved
   by the C standard.  They won't be defined if compiling with -ansi,
   and the headers will break.  We go to some trouble to only change
   #ifdefs where the macro is defined by GCC in non-ansi mode; this
   minimizes the number of headers touched.  */

So gcc build system will change "#ifdef linux" to "#ifdef __linux__".

After talking to Andi, I was proposed to remove that ifdef completely
(instead of changing linux to __linux__ in the header), since it does
not make much sense to include linux/a.out.h on a non linux system.

The following patch does that, is it ok?
