Subject: [PATCH v3] modules_install: make missing $DEPMOD a warning instead of
 an error

From: Randy Dunlap <rdunlap@...radead.org>

When $DEPMOD is not found, only print a warning instead of exiting
with an error message and error status.

Warning: 'make modules_install' requires /sbin/depmod. Please install it.
This is probably in the kmod package.
