From: Johannes Schindelin <johannes.schindelin@xxxxxx>
There was a bug report attached to the copy of 511cfd3bffa (http: add
custom hostname to IP address resolutions, 2022-05-16) in the `git/git`
repository on GitHub, claiming that that commit broke the build on
RedHat Enterprise Linux 6. The most likely explanation is that the
available cURL version does not support the `CURLOPT_RESOLVE` feature.
Let's work around this by warning the user if they configure
`http.curloptResolve` if compiled against a too-old cURL version.

http: support building on RHEL6
This came in via the awkward venue of a commit comment at
https://github.com/git/git/commit/511cfd3bffa685fda0e7c25bfa08082aa0de3a30#commitcomment-77360864.
I looked here [https://curl.se/libcurl/c/CURLOPT_RESOLVE.html] to find
out since when cURL supports CURLOPT_RESOLVE.
