[PATCH] 4.0: New build system doesn't allow custom config file locations

[Tony Vroon]

Good afternoon,

The old build system allowed to customise the location of several key
configuration files through modifying variables such as _PATH_DHCPD_CONF
and _PATH_DHCLIENT_CONF.
This functionality appears to have been lost in the conversion to a
fully autotools-driven build system. The attached patch reintroduces it.
I'm open to comments. This will be used for downstream packaging.

Regards,
Tony V.
