[PATCH] Remove configure checks for and automatic running of autoconf

[Allan McRae]

These checks used to be run when using --with-cvs but were left in
when that option was removed.  Remove these checks as regeneration
of the configure file should be consciously performed.  This also
stops the generation of autom4te.cache in the source directory
while building, allowing the relevant entry to be removed from
.gitignore.
