add --with-tune configure flag

fixes a configure error on Arm64 when passing --with-tune=... to configure:
```
This target does not support --with-tune.
Valid --with options are: abi cpu arch
```
The missing flag sets target tuning to a different value than generic tuning.

gcc/
	* config.gcc: Add --with-tune to AArch64 configure flags.
