configure: Add check for the doc tools
Added checking existence of the doc files converters.
If the XXX tool exists then HAVE_XXX:=y will be written
to the Config file. Example of the configure script output:
TC schedulers
ATM no
IPT using xtables
IPSET yes
iptables modules directory: /usr/lib/iptables
libc has setns: yes
SELinux support: no
Docs
latex: no
WARNING: no docs can be built from LaTeX files
sgml2html: yes
