freebsd-ports/Mk/Uses/kmod.mk
Ed Maste d24567369e on error, remind user of variable used to set src tree location
trying to build kmod ports without a src tree in /usr/src results in a
failure reporitng that the build requires kernel source files in /usr/src.
Mention also the make variable (SRC_BASE) that sets the path as a hint to
users building against a src tree located elsewhere.
