The gcc build has failed for 32-bit host (e.g. i386-emu and arm-emu)
due to mismatch between format specifier and data type.
../grub-core/osdep/devmapper/getroot.c: In function
'grub_util_pull_devmapper':
../grub-core/osdep/devmapper/getroot.c:265:75: error: format '%lu'
expects argument of type 'long unsigned int', but argument 2 has type
'int' [-Werror=format=]
../grub-core/osdep/devmapper/getroot.c:276:80: error: format '%lu'
expects argument of type 'long unsigned int', but argument 2 has type
'int' [-Werror=format=]
This patch fixes the problem by casting the type of calculated offset to
grub_size_t and use platform PRIuGRUB_SIZE as format specifier.

... to factor out fix for glibc 2.25 introduced in 7a5b301e3 (build: Use
AC_HEADER_MAJOR to find device macros).
Note: Once glibc 2.25 is old enough and this fix is not needed also
AC_HEADER_MAJOR in configure.ac should be removed.

grub_util_get_dm_abstraction() does a string comparison of insufficient
length. When using a UUID such as "CRYPT-PLAIN-sda6_crypt", the function
returns GRUB_DEV_ABSTRACTION_LUKS.
This results in the error:
./grub-probe: error: disk `cryptouuid/sda6_crypt' not found.
This appears to be a copy/paste error introduced in:

Depending on the OS/libc, device macros are defined in different
headers. This change ensures we include the right one.
sys/types.h - BSD
sys/mkdev.h - Sun
sys/sysmacros.h - glibc (Linux)
glibc currently pulls sys/sysmacros.h into sys/types.h, but this may
change in a future release.

This was lost when code was refactored. Patch restores previous behavior.
It is still not clear whether this is the right one. Due to the way we
detect DM abstraction, partitions on DM are skipped, we fall through to
generic detection which ends up in assuming parent device is BIOS disk.
It is useful to install GRUB on VM disk from the host. But it also means
that GRUB will mistakenly allow install on real system as well.
For now let's fix regression; future behavior needs to be discussed.
Closes: 45163
