Probably not.  Looking at the bootstrap script (which itself is copied
from gnulib), the sha1sum utility is used to verify language
translation files.  Using it or not is independent of where the gnulib
source tree is stored.  But we are also not using any language
translation files in Octave, so we should not need sha1sum, at least
for now.  The problem is that the check for sha1sum is performed
unconditionally, but it is only used in the update_po_files function,
and that function is only called if the --skip-po option is not
supplied to the bootstrap script and either of the directories "po" or
"runtime-po" exist.  So I think a better solution would be to only
check for sha1sum if it is actually going to be used by the bootstrap
script.

In any case, I would expect that building a current copy of coreutils
should be relatively easy.  You wouldn't need to replace the system
utilities installed in /bin or /usr/bin on your system.  If you don't
want to modify your path to use all of the coreutils utilities in
place of your system utilities, then you could just install the ones
you need like sha1sum in /usr/local/bin or in your personal ~/bin
directory...
