As btrfs is specific to Linux, %m can be used instead of strerror(errno)
in format strings. This has some size reduction benefits for embedded
systems.
glibc, musl, and uclibc-ng all support %m as a modifier to printf.
A quick glance at the BIONIC libc source indicates that it has
support for %m as well. BSDs and Windows do not but I do believe
them to be beyond the scope of btrfs-progs.

tests/fssum.c:599:13: warning: In the GNU C Library, "major" is defined
by <sys/sysmacros.h>. For historical compatibility, it is
currently defined by <sys/types.h> as well, but we plan to
remove this soon. To use "major", include <sys/sysmacros.h>
directly. If you did not intend to use a system-defined macro
"major", you should undefine it after including <sys/types.h>.

We've solved that long time ago and config.h now provides the macros.

The function htonll is not provided by the standard library and we can
replace it by our cpu-to-XX helpers. This switches the endianity of the
checksummed value to LE, but this is not a problem.

Copy from fstests, originally from

Needs libcrypto to link but this check is now missing in configure.
