It would be better to avoid passing the --with-ca-path= option.  We are
attempting to move away from having any compiled-in system-wide location
for the CA trust store.  Each user should be able to specify their
desired trust store using environment variables or other settings.

We currently pass a similar configure-time option to GnuTLS for now, but
only because GnuTLS provides no other way to specify the location of an
old-style system trust store.  We should be able to remove this when we
have the more modern p11-kit system working.

Can you find a way to make 'curl' work without compiling-in a hard-coded
system trust store location?
