Print default options selection for -march,-mcpu and -mtune for aarch64 (PR driver/83193).
2018-08-27 Martin Liska <mliska@suse.cz>
PR driver/83193
* config/aarch64/aarch64.c (aarch64_override_options_internal):
Set default values for x_aarch64_*_string strings.
* config/aarch64/aarch64.opt: Remove --{march,mcpu,mtune}==
prefix. For -mabi do not print '=ABI' in help and use
<option_value> format for -msve-vector-bits and -moverride
options.
