Why do you choose to expose armv8.2-a flag other than using armv8a combine with the extension flags here?
The value 'armv8.2-a' implies 'armv8.1-a' and enables compiler support for the ARMv8.2-A architecture extensions. And the 'lse' extension is the default feature for 'armv8.1-a'. So it seems there is no need to specify 'armv8.2-a' with 'lse'.
According to the meson build code, the default -march config for Cavium is 'armv8-a'. So I think it seems better to keep 'armv8-a' here and add flags for the specific extensions.
The same for thunderx2 configuration.
