POWER9 Hostboot: build attributeOverride if possible rather than never

On ancient host compilers (GCC before 4.8), there isn't the -std=gnu++11
option available, which attributeOverride requires.

Instead of the original fix for this, which was to just never build it,
check to see if the host compiler supports it, and if so, build it.
