RELENG_5 minor src/obj glitches

[Dmitry Morozovsky]

Colleagues,

building RELENG_5 sources one can see the following local modifications slipped 
in:

? usr.bin/lex/lib/.depend
? usr.bin/lex/lib/libmain.po
? usr.bin/lex/lib/libyywrap.po
? usr.sbin/pcvt/keycap/.depend
? usr.sbin/pcvt/keycap/keycap.po

you can see this after make buildworld and then cvs update. 

I tried to catch this via Makefiles but got a bit stuck; however, I'm afraid 
this would prevent building RELENG_5 and related when /usr/src is read-only.

Any clues?

Sincerely,
D.Marck                                     [DM5020, MCK-RIPE, DM3-RIPN]
