[Buildroot] [PATCH] package/libunwind: simplify architectutre dependencies

[Romain Naour <romain.naour@gmail.com>]

Hi Yann, All,

Le 17/04/2017 ? 18:44, Yann E. MORIN a ?crit :
> BR2_ARM_CPU_HAS_ARM already embeddeds the fact that this is an ARM chip,
> so (BR2_arm || BR2_armeb) is forcibly true when BR2_ARM_CPU_HAS_ARM is.
> 
> In other words, BR2_ARM_CPU_HAS_ARM can't be true unless either BR2_arm
> or BR2_armeb itslef is true.
> 
> Simplify the logic accordingly.

The same simplification can be done in package/boost/Config.in.
