Even with our fixes in deterministic_imports.patch the
importlib.metadata package scan was still returning Distribution objects
for empty directories. This interacts badly with rebuilds when recipes
are changing as when a recipe is removed from the sysroot directories
are not removed[1].
In particular this breaks python3-meson-python-native rebuilds when
Meson upgrades from 1.7 to 1.8: the site-packages directory has an empty
meson-1.7.dist-info/ and populated meson-1.8.dist-info/. Whilst it's
deterministic to return the empty 1.7 first, this breaks pypa/build as
it looks through the distributions in order.
We had discussed this with upstream previously and there's a more
comprehensive fix upstream (actually in importlib_metadata, not cpython)
which ensures that valid distribution objects are listed first. So we
can drop our patch and replace it with a backport to fix these rebuilds.

ctypes.util.find_library depend on run external programs(ldconfig, gcc,
objdump or ld) to get the pathname, if none of above are installed, None
is returned. Previously, RDEPENDS to ldconfig is added to ensure it
always work when installed.
This commit change it to RRECOMMENDS, this allows user who don't use
function find_library could remove ldconfig from image by
PACKAGE_EXCLUDE

In oe-core, function ldconfig_postinst_fragment use exist of
/sbin/ldconfig to decide if ldconfig is runned to generate the cache,
and function _run_ldconfig will run ldconfig to generate cache during
generate rootfs. ldconfig.service is actually not used since we have
generate ld.so.cache during do_rootfs, refer[1][2][3]. ldconfig
dependency is necessary when ldconfig not in DISTRO_FEATURES.
The reverted commit causes regression when ldconfig not in
DISTRO_FEATURES, before, without ldconfig in DISTRO_FEATURES,
ctypes.util.find_library(name) can find the lib if it is installed, now,
since ldconfig is not installed, ctypes.util.find_library(name) cannot
find the lib even if it is installed.
Here is one usecase(gtk+3 lib is installed, ctypes.util.find_library
used to find the lib):
