Allow passwordless login in addition to usual login with password, when
creating 'root' user during install.
The effect of that change is that "local administrators" group are
allowed to connect as root user. This is done via gssapi authentication
plugin.
Clients that are not aware of gssapi client plugin, can still login with
password credentials.
krb5-config (used by FindGSSAPI) returns `-lkrb5 -lk5crypto -lcom_err`
but only libkrb5 is actually used by the gssapi plugin. The other two
result in unneeded dependencies unless they're tagged optional when
linked with --as-needed.
Some distributions use --as-needed automatically, which causes our
builds to differ from srpm builds, introducing failures in buildbot.
Let's always use --as-needed for gssapi plugin
This gives a short overview over found/missing dependencies as well
as enabled/disabled features.

Compiler warnings generated on building MariaDB server for BSD has the same
reason as in case building is performed on MacOS. Both platforms do use
clang as a C/C++ compiler. So, fix the compiler warnings in case the compiler
is clang doesn't matter what kind of building platform do we use for building.
This is a follow-up patch for the following bug reports:
MDEV-23564: CMAKE failing due to deprecated Apple GSS method
MDEV-23935: Fix warnings generated during compilation of
plugin/auth_pam/testing/pam_mariadb_mtr.c on MacOS
Some GSS-API functions like gss_import_name(), gss_release_buffer()
used in plugin/auth_gssapi and libmariadb/plugins/auth are marked
as deprecated in MacOS starting from version 10.14+. It results in
extra warnings output on server building.
To eliminate extra warnings the flag '-Wno-deprecated-declarations'
has been added to compiler invocation string for those source
files that invoke deprecated GSS-API functions.
* FreeBSD calls amd64 what Linux calls x86_64
* signal returns void (*)(int)
* struct pam_message has char*, not const char*
* krb5_free_unparsed_name exists, but is deprecated
