[Samba] build samba manpages in CentOS 7

[Klaus Hartnegg]

Hi,

I tried to build samba 4.1.12 in freshly installed CentOS 7 following 
the descriptions on
https://wiki.samba.org/index.php/Build_Samba
https://wiki.samba.org/index.php/OS_Requirements

yum reports that it does not know the packages xattr, xsltproc, docbook.

Configure complains that perl is missing.

After adding perl, running configure, make, and make install, there are 
no man pages anywhere in /usr/local/samba.

How can I build these man pages?

Klaus
