GCC 14 newly by default treats as errors a number of situations which
before were only warnings.  For more information see
https://gcc.gnu.org/gcc-14/porting_to.html and meta bug #1220571.

Because of this, package openssh fails to compile.  This can be seen online
at:
https://build.opensuse.org/package/live_build_log/openSUSE:Factory:Staging:Gcc7/openssh/standard/x86_64

It can be reproduced locally with command: osc build --clean
--alternative-project home:rguenther:nextgcc

We most likely need patches listed at:

The (first) error (that halts the build) is:

[   48s] ldapconf.c: In function ‘process_config_line’:

did you mean ‘strtok’? [-Wimplicit-function-declaration]
