"env name=value ... cmd ..." is just a pessimized way of doing "name=value ... cmd ..." in real shells. Set the environment (without using env(1)) before starting xargs so that env(1) is not needed in "xargs env name=value ... cmd ..."

# Unified Makefile for building kenrels. This includes all the definitions
|
|
# that need to be included after all the % directives, except %RULES and
|
|
# things that act like they are part of %RULES
|
|
#
|
|
# Most make variables should not be defined in this file. Instead, they
|
|
# should be defined in the kern.pre.mk so that port makefiles can
|
|
# override or augment them.
