Subject: On i386 compile the back-end with EISA support as well as the EISA
 front-end if the dpt(4) module is built along with a kernel that includes
 eisa(4) or when compiling it stand-alone (logic based on the corresponding
 ISA logic in sys/modules/sound/sound/Makefile). As as side-effect this fixes
 the stand-alone build of the dpt(4) module after dpt.h 1.17, dpt_eisa.c 1.22
 and dpt_scsi.c 1.55.
