[Buildroot] [PATCH 04/15] arch: add BR2_ARCH_NEEDS_GCC_AT_LEAST_9

[Yann E. MORIN <yann.morin.1998@free.fr>]

On 2019-05-06 20:30 +0200, Romain Naour spake thusly:
> This new symbol will be used by architectures introduced with gcc 9 and
> by external toolchains based on gcc 9.
>

This must be added after you actually introduce gcc-9.

I.e.:

  - add gcc-9
  - add this new symbol
  - add the ne archs or ocres that need gcc-9

If we apply just this patch, it does not make sense at all: we'd have a
way to specify that we require something that we can't even provide...

Regards,
Yann E. MORIN.
