samba - Apr 2016 - Is the location of the "winbindd_privileged" directory hard-coded?

Even whith an explicit build time configuration of

--with-statedir=/usr/local/samba/var 
--with-privileged-socket-dir=/usr/local/samba/var/lib

the final path still is "${LOCALSTATEDIR}/winbindd_privileged" instead
of "${LOCALSTATEDIR}/lib/winbindd_privileged".

Yet, "samba -b" reports

WINBINDD_PRIVILEGED_SOCKET_DIR: /usr/local/samba/var/lib/winbindd_privileged

"testparm -sv" and "samba-tool -v" give "winbindd
privileged socket
directory = /usr/local/samba/var/lib/winbindd_privileged"

"man winbindd" states that the winbindd privileged pipe should be in 
"$LOCKDIR/winbindd_privileged/pipe" which is also not correct.

A FHS installation places the "winbindd_privileged" directory in the 
expected place "/var/lib/samba/winbindd_privileged".

The /usr/local installation does not respect its own default:

--with-privileged-socket-dir=PRIVILEGED_SOCKET_DIR
      privileged socket directory
      [STD-Default: ${LOCALSTATEDIR}/lib]
      [FHS-Default: ${LOCALSTATEDIR}/lib/samba]
