[Buildroot] [PATCH 1/2] gcc: disallow 4.8.x for ARMv8 cores

[Buildroot] [PATCH 1/2] gcc: disallow 4.8.x for ARMv8 cores

[Peter Korsgaard]

Notice: A53/A57 were in fact supported in aarch64 mode in 4.8 (in aarch32
mode only from 4.9), but it doesn't handle --with-abi, and as there is
unlikely to be any aarch64 based legacy projects unwilling to use a newer
GCC version it is simpler to disallow it for all modes.
