I think that depends on how you build GnuTLS.  If it is configured to
link with libtasn1 installed on the system (default), you would anyway
need to update it; I suggest any build failure to the upstream issue
tracker: https://gitlab.com/gnutls/libtasn1/-/issues

Otherwise, if it is configured to use libtasn1 bundled in GnuTLS release
(i.e., with --with-included-libtasn1), upgrading to GnuTLS 3.8.0 might
be an option, as it includes 4.19.
