Warner created this feature only to fit one case: where you build kernel
from its canonical place, /usr/src/sys/<arch>/compile/<KERNEL>, then
${.CURDIR}/../../../ will match the the correct SYSDIR.  The below
patch makes it work in all cases.  If $S is absolute, it's used,
otherwise ${.CURDIR}/$S is used:

# pwd
/usr/obj/usr/src/sys/HAMMER
# make -V S -V PORTSMODULESENV -DPORTS_MODULES
/usr/src/sys
SYSDIR=/usr/src/sys

# pwd
/sys/amd64/compile/GENERIC
# make -V S -V PORTSMODULESENV -DPORTS_MODULES
../../..
SYSDIR=/usr/src/sys/amd64/compile/GENERIC/../../..
