[Buildroot] [PATCH 1/2] add host arch detection and Kconfig (BR2_HOSTARCH)

[Jean-Christophe PLAGNIOL-VILLARD]

This will allow to install binary package only if they are supported by the
host. As example Atmel SAM-BA (x86 only).

 If it's going to be any use, I guess we still need to be able to
distinguish arm/armeb and sh/sh64.  But I don't know how these look
in the uname.

If you can found one sh64 board good luck I may have one somewhere but not
even sure I can still found a sh64

for arme if you can found a board with enough power power to build something on it
as big as buildroot

today the Cortex A15 and A9 are little endian

it's the for ping

did I need to understand that noe one care of non x86 host?

To me it is more of a question of tradeoffs. Either we do it really
right and use this kind of infrastructure for the external toolchains as
well (where it really matters), or we decide the extra complexity isn't
worth it for the few non-x86 users.

I haven't made up my mind about this yet, but am leaning towards the
2nd.

as a non x86 user I really care

and as the ARM A15 will come soon on the market for serer as example it will
be more and more problematic for binary package

  ... except that it's not really problematic.  The only problem is that you can
configure buildroot to download something that won't actually run on your
system.  This problem is a lot worse for external toolchains than for sam-ba.

  That said, the patch is really simple and doesn't create a maintenance burden.
Having it in paves the way for disallowing other downloaded host binaries, and
for downloading host binaries for the correct platform.  Therefore:

Acked-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>

  Jean-Christophe, maybe it's worthwhile to resend and perhaps add
a patch for external toolchains as well?

  Regards,
  Arnout
