You are not using an ARM build of gcc, you are using an AArch64 build,
the available options are documented here:

https://gcc.gnu.org/onlinedocs/gcc-7.4.0/gcc/AArch64-Options.html#AArch64-Options

If you were running an ARM compiler on an ARMv8 CPU then it could make
sense to specify some other options, you are not.
