We fetch the test bins from another repo during the testing builds, it works fine on x86 builds, but fails on ARM64 one:
git clone --depth 1 https://github.com/radareorg/radare2-testbins bins
Cloning into 'bins'...
fatal: unable to access 'https://github.com/radareorg/radare2-testbins/': Could not resolve host: github.com
make: *** [bins] Error 128
make: Target 'all' not remade because of errors.
+exit 1
