[committed 03/11] aarch64: Eliminate a temporary variable.

[Andrew Carlotti]

The name would become misleading in a later commit anyway, and I think
this is marginally more readable.

gcc/ChangeLog:

        * config/aarch64/aarch64.cc
        (aarch64_override_options): Remove temporary variable.
