[Buildroot] [PATCH 0/2 v3] arch: allow passing compile flags (branch yem/arc-atomic)

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

Hello All!

This series makes it so that architectures can set compilation flags,
passed down via the wrapper.

This is then used by arc to enforce -matomic for those cores that need
it, namely arc7x0, as reported by Alexey:

    https://patchwork.ozlabs.org/patch/1087480/
    https://patchwork.ozlabs.org/patch/1087471/

Changes v2 -> v3:
  - fix 'y' -> 'yy' in condition

Changes v1 -> v2:
  - move condition that was previously in package/Makefile.in  (Alexey)


Regards,
Yann E. MORIN.
