That's the reason, right there: the configure script decided it
couldn't find GnuTLS installed whose version is at least 2.12.2:

> 167 checking for gnutls >= 2.12.2... no

AFAICT, Emacs 29.4 was making the same test, so there's some other
factor here at work.  Did something change wrt GnuTLS between the time
you built Emacs 29.4 and the time you tried to build 30.0.91?  Are you
sure you have the header files needed for developing programs with
GnuTLS?

In any case, please post config.log which was created by running the
configure script, it should tell the details regarding the failed
test.

And if worse comes to worst, you can always use the above advice
(although building Emacs without GnuTLS is not recommended).
