libtasn1 test suite fails on macOS Bug Sur with Apple Silicon

[Roman Bolshakov]

Hello,

I'm seeing the test failures on macOS and there's a concern that the
behaviour might affect GnuTLS and ultimately QEMU test suite.

Are there any ideas of what might be causing it? Any help is
appreciated.

Thanks,
Roman
