Hi,

i'm getting the following build error with buildroot + powerpc64le:

Linux kernel version: 4.4.305

Makefile says Checking for ELS_DTAG_LNK_INTEGRITY in /usr/include/scsi/fc/fc_els.h ... yes which indicates that it checks the host header not the target one.

Sorry, my fault, didn't notice the Makefile change 6b7d47be3b23 ("multipath-tools: Makefiles: simplify code for include dirs")

Thanks for double-checking.
