aarch64: Small config.gcc cleanups
The aarch64-option-extensions.def parsing in config.gcc had
some code left over from when it tried to parse the whole
macro definition. Also, config.gcc now only looks at the
first fields of the aarch64-arches.def entries.
gcc/
* config.gcc: Remove dead aarch64-option-extensions.def code.
* config/aarch64/aarch64-arches.def: Update comment.
