Freeradius build failure with Librssl 3.5

[orbea]

OS: Gentoo libressl: 3.5.2 freeradius: https://github.com/FreeRADIUS/freeradius-server/commit/5517ed19ca059735b07049542a9ea96ded9f3201

The build fails with libressl and it seems there have been multiple changes upstream since the version currently in OpenBSD.

This issue is blocking me from trying to get an unrelated slibtool build issue fixed in Freeradius upstream, any help would be appreciated.
