More and more machines and architectures are added without keeping the lists up-to-date. Replace the lists with a pointer to the reference directory. The same kind of pointer is used for the supported compilers and environments. Signed-off-by: Thomas Monjalon <thomas.monjalon@6wind.com> Acked-by: Konstantin Ananyev <konstantin.ananyev@intel.com>
