[Buildroot] [PATCH] package/harfbuzz: work around arc gcc10 bug

[Yann E. MORIN]

Giulio, All,

On 2021-09-08 23:57 +0200, Giulio Benetti spake thusly:
> With BR2_GCC_VERSION_ARC=y(arc gcc10) harfbuzz package exhibits a gcc bug
> that makes build to fail. This bug is found only in official arc gcc10
> provided by Synopsis, so we can't use the BR2_TOOLCHAIN_HAS_GCC_BUG_
> approach since bug can't be even filed in gcc bugzilla.
> To work around this, if BR2_GCC_VERSION_ARC=y we force using -O0.

Good enough for me! 👍
