Hum, this is something I didn't think of when merging the series from
Yann regarding those options. You are now removing this dependency
because the toolchain uses gcc 7.x. However, it means that as soon as
we introduce BR2_ARCH_NEEDS_GCC_AT_LEAST_8, we will have to go and edit
each and every toolchain that uses gcc 7.x to add
a !BR2_ARCH_NEEDS_GCC_AT_LEAST_8 dependency. Not very practical :-/
