freebsd stable - Mar 2008 - RELENG_7_0 buildworld failure on read only source tree

Hi,

We have been building RELENG_6_x source trees from read only NFS file 
systems for well over a year now with out any problems.  However I have 
just tried to do "make buildworld" on a RELENG_7_0 source tree from 
yesterday and it failed to build with the following error:

Should it be possible to build RELENG_7_0 with a read only source tree?

Thanks

This can be worked around, I think touching the Makefile would do the 
trick.  IIRC David (cc'ed) has fixed the Makefile at some point this 
January while he is updating the base cvs(1) for this exact issue, maybe 
we should MFC the changeset to RELENG_7?
