Due to a bug in the glibc headers the macros makedev(), major() and minor() where avaialble by including sys/types.h. This bug was addressed in glibc-2.25 by introducing a warning when these macros are used. Since Xen is build with -Werror this new warning cause a compile error. Use sys/sysmacros.h to define these three macros. blktap2 is already Linux specific. The kernel header which was used to get makedev() does not provided it anymore, and it was wrong to use a kernel header anyway.
