RFC: first patch for getting arch-specific stuff out of asm-generic/barebox.lds.h

[Robert P. J. Day]

  looking for comments on this patch as simply the *first* tweak to
start cleaning arch-specific content out of that barebox.lds.h.
here's the incredibly simple change to handle just x86:

===== start =====

 #include <mach/barebox.lds.h>
 #endif

===== end =====

  of all the tests in the asm-generic file, the x86-related test is
unique in that it would end up including nothing but macro
definitions, so all the above does is remove that check from the
asm-generic file and explicitly put it into the x86 file -- it
*appears* that this has the same effect, and i tested it by building a
regular sandbox, which worked fine.  (does that represent a reasonable
test?)

  there's more that can be done, but the above at least gets rid of
one silly test in asm-generic/barebox.lds.h that doesn't need to be
there.

  thoughts?  if it looks reasonable, i can submit it as an official
patch.
