configure --enable-code-coverage fails

[gaoxingwang]

I did this

I am trying to get a code coverage report, so i added an option '--enable-code-coverage'.
It looks like this:

./configure --enable-code-coverage  ... --with-libpsl --with-libssh

However,./configure failed with the following error message：

configure: error: couldn't find libraries for gethostbyname()

I expected the following

./configure--enable-code-coverage should be available.
