description:
Remove tests.7 in objdir before copying to it.

If one's source tree has non-writable files (because of CVSREAD=t, or
someone else owns it, or it's on some read-only filesystems, some
other reason), recently-added makefile code would cp tests.foo.7 in
the sources to tests.7 in objdir, preserving permissions, but not
forcing the copy.  A subsequent copy would result in an error, failing
the build.  Therefore, rm -f the target file before doing the copy.

(Arguably there should some standard support for this, but copying
files from the source directory to objdir is quite unusual.)
