make-kpkg target failing for v3.1

[Steven R. Wright]

while trying to build kernel v3.1 today,  i ran into this error:

****************************************
create_md5sums_fn () { cd $1 ; find . -type f ! -regex './DEBIAN/.*' ! 
-regex './var/.*'      -printf '%P\0' | xargs -r0 md5sum >

i have not encountered this error building the kernel in v3.0.4 and 
before (i generally build and install most of the new stable releases, 
and have done so since v.2.4). the command i used, and always have, was:
make-kpkg --initrd --rootcmd fakeroot kernel_image


there is a difference in the perms in a 3.1 build tree vs. a 3.0.4 tree

while it certainly *looks* like the "chmod og=rX" should take place in 
the 3.0.4 build process,  the directory does not reflect it,  and the 
dpkg-deb process is content and completes.
