After that chanage, "MAXPARTITIONS" constant is not for the target port.
If host's MAXPARTITIONS is larger than a value of the target label and
target endianness is different from the build host, bswaplabel() could
overwrite data beyond the disklabel and primary boot stored after
LABELSECTOR in images might be corrupted.
This fixes boot failure of sun2 liveimage built by
"build.sh -U -m sun2 release live-image"
on TME.
Should be pulled up to netbsd-7.

This is used by disk tools such as disklabel(8) to dynamically decide is
the undelyling platform uses a disklabel-in-mbr-partition or not
(instead of using a compile-time list of ports).
getlabelusesmbr() reads the sysctl kern.labelusesmbr, takes its value from the
machdep #define LABELUSESMBR.
For evbmips, make LABELUSESMBR 1 if the platform uses pmon
as bootloader, and 0 (the previous value) otherwise.
for some reason. (But I have no idea why that would be -- if you have one
of these really ancient partitions and you're about to run disklabel, you
can easily run fdisk first and change the partition type to NetBSD.)
As it stands, the code will munch FreeBSD installs under some
circumstances, which is really not acceptable behavior.
The code, along with the kernel support that's been disabled by
default for several years, and some related but less dangerous code in
sysinst, should prboably be removed entirely after -6 is branched.
Discussed on tech-kern and tech-userlevel; closes PR 44496.
This is also almost certainly the cause of PR 42521 and PR 38841.
printed. There's now a lot of PRIu16 and PRIu32, some PRIu8, some
SCNu32, and a few cases where %u and %d were reversed. Multiplication
of 32-bit and 8-bit values is cast to uint64_t and printed with PRIu64.
Inspired by a report from Patrick Welche on current-users.
(treating a target disk as a regular file and suppressing ioctl(2)s)
on reading/writing disklabel in a target file.
This allows cross build enviroment creating bootable disk images
for targets in different endian.
No functional changes to native (non-tools) disklabel(8) command.
Closes PR toolchain/42357.
Instead, use proper macro defined in Makefile per ${MACHINE_ARCH}.
__${MACHINE_ARCH}__ doesn't represent an architecture of tool's target
but an architecture of binaries being compiled, so required features
are not prolery enabled or unintentionally enabled on certain host
and target combinations during src/tools build.
- Use %.40g rather than %g when printing sectors and MB for existing
partition size/offset.
