Subject: configure: better diagnostics if hyper is built wrong
X-Git-Tag: curl-7_81_0~167

configure: better diagnostics if hyper is built wrong

If hyper is indeed present in the specified directory but couldn't be
used to find the correct symbol, then offer a different error message to
better help the user understand the issue.

Suggested-by: Jacob Hoffman-Andrews
Fixes #8001
