Needs to be predicated on the existence of Perl and pod2man.  And
therefore we need to continue shipping gcov.1 etc with release
bundles.

Not safe in the presence of simultaneous builds from the same
directory.  You need

	$(POD2MAN) gcov.pod >$(srcdir)/gcov.1.T$$; \
	if test $? -eq 0; \
	then mv -f $(srcdir)/gcov.1.T$$ $(srcdir)/gcov.1; \
	else rm -f $(srcdir)/gcov.1.T$$; \
	fi

(If anyone knows a shorter way to write that I'd be delighted to know.)
