Single quotes:

make MODULE_TOPDIR="$GISBASE" \
   ARCH_INC="'-I$GISBASE/include' '-I${MYINST_DIR}/include' '-I$TMPDIR/$DIST_DIR/include'" \
   ARCH_LIBPATH="'-L$GISBASE/lib' '-L${MYINST_DIR}/lib' '-L$TMPDIR/$DIST_DIR/lib'" \

This approach will work so long as the variable is only used within
commands. The value (which doesn't include the outer-most double
quotes) will be substituted verbatim (including the single quotes)
into the command which is passed to the shell.

Make itself doesn't have any quoting mechanism, so you can't have
spaces in any path which is used as part of a target or prerequisite,
or an "include" directive, or which is processed by make functions
(patsubst, wildcard, etc).
