Well, d66cd067f3 was written because if you install a very minimal
system, you may not have the SSL certificates installed, which prevents
any download from https:// website. So I added a quick check for that.

However, apparently, the location of such certificates is not fixed
between various systems, so clearly my patch doesn't work properly.

I see two options here:

 (1) Apply your patch, and assume that in most systems, SSL
     certificates are always installed. The case I had what when you
     create a very minimal Debian system, but most people probably use
     a more full-featured system, and it's pretty likely that SSL
     certificates are already installed.

 (2) Replace the test by a test that wget some well-known https:// URL,
     and if it doesn't work, say that SSL certificates are not
     available. But I don't like this too much, because this means that
     at every invocation of 'make', Buildroot will try to download
     something from the network.

So, for now, I believe option (1) is the only viable one, unless there
is some local command that allows to check whether SSL certificates are
installed or not.

Best regards,

Thomas
