scripts: removes uses of <asm*/errno.h> in favor of <errno.h> ...

We can't assume <asm/errno.h> to be available on non-Linux hosts.
Furthermore, errno constants values aren't fixed and passing them
to libc perror(3)/strerror (3) would yield wrong results.
Fix this by using the standard <errno.h> header instead.

scripts: mkimage: s/fdatasync/fsync/ on macOS & OpenBSD ...

fdatasync is an optional part of POSIX and mkimage uses the more general
fsync on Sun and FreeBSD as an alternative. Add macOS[1] and OpenBSD to the
list as well.

This is in-line with what U-Boot does since 31cbe80c33
("mkimage: fix compilation issues on OpenBSD").

[1]: macOS >=10.7 does indeed define (but not declare anywhere) a seemingly
     working fdatasync, but we won't consider this here.

scripts: includes: restrict strlcpy prototype to glibc ...

Defining strlcpy here clashes on macOS, which has some compiler magic
around their strlcpy declaration. Fix this by inverting the check
to declare the prototype only if we are on __GLIBC__. As uClibc may
define __GLIBC__ as well, check for absence of its __UCLIBC__.

This is in-line with what Linux has been doing since 0215d59b15
("tools lib: Reinstate strlcpy() header guard with __UCLIBC__").

kbuild: Use ls(1) instead of stat(1) to obtain file size ...

stat(1) is not standardized and different implementations have their own
(conflicting) flags for querying the size of a file.

ls(1) provides the same information (value of st.st_size) in the 5th
column, except when the file is a character or block device. This output
is standardized[0]. The -n option turns on -l, which writes lines
formatted like

  "%s %u %s %s %u %s %s\n", <file mode>, <number of links>,
      <owner name>, <group name>, <size>, <date and time>,
      <pathname>

but instead of writing the <owner name> and <group name>, it writes the
numeric owner and group IDs (this avoids /etc/passwd and /etc/group
lookups as well as potential field splitting issues).

The <size> field is specified as "the value that would be returned for
the file in the st_size field of struct stat".

To avoid duplicating logic in several locations in the tree, create
scripts/file-size.sh and update callers to use that instead of stat(1).

LICENSES: remove empty other, exceptions directories ...

These directories were originally added as they were required for
spdxcheck.py, which upstream checkpatch.pl invokes.

As git doesn't index empty directories, they contained empty
.gitignore files. As these files were 0 bytes, make distclean now
removes them.

We already patch checkpatch.pl, so we will just patch spdxcheck.py
when we add it and get rid of these directories.
They can be added back should the need arise.
