Original PR filed as ports/165994

SRC_BASE is being used before being defined in several ports. it happened to 
work anyways in most cases because the main use of SRC_BASE is for checking if
${SRC_BASE}/sys/ (/usr/src/sys/) exists, and if SRC_BASE is empty, it just
checks for /sys/ which does exist on most systems as a symlink to /usr/src/sys/.

Port maintainer (jkim at FreeBSD.org) is cc'd.
