[svn-r10215] Purpose:

Configure feature

Description:
On some platforms with some compilers, automake's dependency tracking
is silently disabled.  This can be confusing for developers.

Solution:
Set configure to enable dependencies all the time unless the user
explicitly disables them (using the configure flag
--disable-dependency-tracking) or a site file overrides the default
(as is the case on IRIX).

Platforms tested:
sleipnir, mir
