Cortex-a78ae is newer than GCC 8, so you get this error.
One of the following options would solve this Issue.
Option 1: Upgrade the GCC to at least an 11.x version
The resulting build would be the most performant for Cortex-a78ae CPU.
Option 2: Force meson to do a generic build by passing -Dplatform=generic
The resulting build may not be as performant as the one produced by options 1.
It will use only following march=armv8-a+crc as defined here
