NSURLConnection Test aborts on Debian 11 (aarch64)

[Hugo Melder]

Hi,

I’m currently in the process of automating Debian and RPM packaging, yet on 
aarch64 the NSURLConnection test aborts while trying to fetch a remote website 
(google). I’ve linked base using lld and later gold (just to confirm that this 
is not a linker issue). The test fails at 
Tests/base/NSURLConnection/basic.m:56. An exception is thrown from an 
NSRunLoop. Sadly, I’m not familiar with the NSRunLoop source code.

Backtrace in LLDB:
