Take the CentOS curl src.rpm package and add exit 1 to the beginning of 
%check so that it exits quickly w/o removing the BUILDROOT in mock.

Start changing the configure switches disabling stuff and look at the 
library and the curl binary with ldd.

You'll see the configure switches reduce what the library links against 
but not what the binary links against. It's configure is clearly broken.

I tried disabling all the RHEL patches but the behavior is the same, 
it's not caused by a patch.
