Running configure twice will most likely cause test failures

Currently when running configure without any options and running the test suite will pass successfully. If one the runs configure again but this time with an option, for example --debug-nghttp2 the will be test failures. The same goes for other options like --without-ssl.

I think this might be related to 6dd4a07. I've reverted this locally to test and that does resolve the issue but wanted to see if this could perhaps be fixed without reverting first.

@danbev can you check if #23355 fixes that.
