arch/Config.in.x86: drastically simplify the BR2_ARCH definition

Browse Source 
The BR2_ARCH definition is like this:

 * i486 for the i486 platform
 * i586 for a small number of platforms
 * i686 for all other x86 platforms when used in 32-bit, but we
   enumerate their entire list
 * x86_64 for all x86 64-bit platforms

The list for i686 is long and needs to be extended everytime a new
platform is added, with no added value.

So this commit simplifies that by replacing this long list with just:

   default "i686"	  if BR2_i386

This works because Kconfig guarantees us that if an i386 platform
matches an earlier case (i486 or one of the i586 platforms), the i486
and i586 earlier in the list will match.
