FIX: to all makefiles in src/Mail

[utzoo!decvax!ucbvax!dist2]

	None of these makefiles properly give the DESTDIR declarations
as /usr/ucb.  The necessary modifications are:

	diff src/Mail/makefile.40.old src/Mail/makefile.40
	5c5
	< DESTDIR=/usr/src
	---
	> DESTDIR=/usr/ucb

	diff src/Mail/makefile.cc.old src/Mail/makefile.cc
	5c5
	< DESTDIR=/usr/new
	---
	> DESTDIR=/usr/ucb

	diff src/Mail/makefile.cory.old src/Mail/makefile.cory
	4c4
	< DESTDIR=/usr/src
	---
	> DESTDIR=/usr/ucb

	diff src/Mail/makefile.v6.old src/Mail/makefile.v6
	5c5
	< DESTDIR=/usr/src
	---
	> DESTDIR=/usr/ucb

	diff src/Mail/makefile.v7.old src/Mail/makefile.v7
	5c5
	< DESTDIR=/usr/src
	---
	> DESTDIR=/usr/ucb

	diff src/Mail/makefile.vax.old src/Mail/makefile.vax
	5c5
	< DESTDIR=/usr/src
	---
	> DESTDIR=/usr/ucb

	diff src/Mail/makefile.ing.old src/Mail/makefile.ing
	5c5
	< DESTDIR=/usr/src
	---
	> DESTDIR=/usr/ucb

This corrections is necessary for all tapes written before 10/11/81.
