AArch64: Add support for --with-tune
Add support for --with-tune. Like --with-cpu and --with-arch, the argument is validated and transformed into a -mtune option to be processed like any other command-line option. --with-tune has no effect if a -mcpu or -mtune option is used. The validating code didn't allow --with-cpu=native, so explicitly allow that.
