Yes, that should work. Note also that you cannot do 'cd /usr/src/usr.bin ;
make SUBDIR="last leave"' anymore.

AL>Does this also apply to environment variables (CFLAGS="foo bar" make)?

No. Environment variables have lowest priority - command line variables
and makefiles override them. But you should be able to say
CFLAGS="foo bar" make -E CFLAGS to move up CFLAGS in the priority list.
