Add "native" as a valid option value for -march= on aarch64 (PR driver/83193).
2018-02-21 Martin Liska <mliska@suse.cz>
PR driver/83193
* config/aarch64/aarch64.c (aarch64_print_hint_for_core_or_arch):
Add "native" as a possible value.
* config/aarch64/aarch64.h (HAVE_LOCAL_CPU_DETECT): Define
the macro when native cpu detection is available.
