Not able to run benchmarking tests

Hello,

I cloned x264 and tried to run benchmarking tests using the following commands:

$ git clone https://code.videolan.org/videolan/x264.git

$ cd x264

$ ./configure

$ make

$ make checkasm

$ ./checkasm8 --bench

$ ./checkasm10 --bench

I am getting the following output (both with checkasm8 and chechasm10):

x264: using random seed 3554438459 x264: ARMv8 Illegal instruction (core dumped)

When I try to execute benchmarking tests for a specific function (for example ./checkasm8 --bench=var2_8x16_neon), the unit tests run but then again I am getting a core dumped:

`x264: using random seed 3688374400 x264: ARMv8

My machine is an ARM Neoverse-N2.

Can you please tell me what I am doing wrong?

Thank you in advance, Akis
