In the 0.191 update dirname was used instead of <libgen.h> to fix the
poisoned basename error:
/usr/include/libgen.h:35:9: error: attempt to use poisoned "basename"
35 | #define basename __xpg_basename
However, doing this has lead to libelf.a pulling in xmalloc, xstrdup and
friends and statically linking them thus leading to a symbol name conflict
with FRR host build and anything else that links against libelf and uses
xmalloc and friends.
Well, it turns out that upstream has added a helper[1] for basename so it
can compile with musl 1.2.5 which dropped the basename declaration, but it
also means that we must NOT include <libgen.h> and that poisoned error is
intentional and added to prevent duplicate basename definitions.
This also means that for macOS we dont need to do any additional header
inclusions as the new helper takes care of basename.
So, to fix the symbol conflict we can simply drop the <dirname.h> inclusion
and build from elfutils.
Tested on Fedora 40 as well as macOS 14.4.1.

Quilt refresh combined two sets of changes to the same file.
The switch from using libgen.h to dirname.h because of function poisoning
from gnulib's import of basename() was added as a new patch hunk instead
of an edit to the original one.
The original patch hunk was to fix build errors on an earlier version of
elfutils before the "dirname" module was being imported to fix further
build errors with the 0.191 version.

A false tdestroy() function was added in order to make elfutils build on
macOS again. A previous commit added declarations for a real version of
tdestroy() into gnulib, which is already imported, as well as the
preprocessor flags and the triggers for the Makefile.am conditional in
order to include the source to be built.

Instead of editing the SUBDIRS variable with a patch, it can be overriden
at the end of the command line when invoking Make.
This tool has a series of recursive Makefiles in each subdirectory,
therefore SUBDIRS is set to a pattern of Make functions so that the result
is variable depending on the current subdirectory that Make is being
invoked in.
It's not necessary to have gnulib-cache.m4 in EXTRA_DIST since we don't
need to re-import after packaging this in the SDK, so get rid of the
entire patch hunk for ./Makefile.am
