The top level Makefile adds, if the environment variable DESTDIR is
defined, the according include and link directory to CFLAGS and LDFLAGS
to build all userspace tools against dependencies from this repository
and not the system.
If CFLAGS or LDFLAGS are specified by the user, e.g.
DESTDIR=~/destdir CFLAGS=-Dfoo LDFLAGS=-Lbar make install
use the override directive to force adding DESTDIR paths to the user
specified CFLAGS or LDFLAGS.
Note that
DESTDIR=~/destdir make CFLAGS=-Dfoo LDFLAGS=-Lbar install
does not work, since in sub-directories the internal make options take
precedence over the overridden environment variables in the top
Makefile.
