Feeding the output of /dev/urandom into /dev/random is pretty much insane
and not something we should encourage.
I can't really imagine a scenario where this would be a sensible idea since
/dev/urandom if effectively derived from /dev/random.
This changes the tool to default to /dev/hwrng which makes much more sense,
feeding hardware entropy into the random pool. In the QEMU case, this will
feed entropy from the host into the guests which is also what we want.
Yes, this change will cause rngd not to start if /dev/hwrng isn't present,
but it isn't needed if that isn't so I don't see this as a bad thing.
(https://wiki.archlinux.org/index.php/Rng-tools has a section in red which
agrees with the above, "this is a really bad idea, since you are simple
filling the kernel entropy pool with entropy coming from the kernel itself!")

uclibc support was removed a while ago and musl works much better. Start to
remove the various overrides and patches related to uclibc which are no longer
needed.
uclibc support in a layer would still be possible. I have strong reasons to
believe nobody is still using uclibc since patches are missing and I doubt
the metadata even parses anymore.

When testing core-image-sato with hardening flags, it fails with
SIGSEGV in libc.so during relocation time
This is due to relocations in .text [textrel]
build QA points it out clearly during qemux86 build as well
AssertionError: 2 != 0 : Log: /mnt/a/oe/build/tmp/work/qemux86-bec-linux-musl/core-image-sato/1.0-r0/dmesg_output.log

When using systemd as init rng-tools is causing a circular dependency
between units,
[ 7.706250] systemd[1]: basic.target: Found ordering cycle on
basic.target/start
[ 7.706934] systemd[1]: basic.target: Found dependency on
sysinit.target/start
[ 7.707795] systemd[1]: basic.target: Found dependency on
rng-tools.service/start
[ 7.708692] systemd[1]: basic.target: Found dependency on
basic.target/start
[ 7.709461] systemd[1]: basic.target: Breaking ordering cycle by
deleting job rng-tools.service/start
[ 7.710404] systemd[1]: rng-tools.service: Job rng-tools.service/start
deleted to break ordering cycle starting with basic.target/start
The problem is related to systemd running sysvinit scripts by default
add dependency of basic.target for sysvinit script so when sysvscript
is at rcS is added also as dependency of sysinit.target causing a
cirular dependency in this case: basic.target -> sysinit.target ->
rng-tools.service -> basic.target.

The underquoted m4 caused build failures if libgcrypt wasn't present. The floating
dependency on libgcrypt was just plain incorrect, particularly given the incorrect
libgcrypt RDEPENDS. Change to use PACKAGECONFIG an default to on.

musl doesn't provide argp, so we need argp-standalone, as we do for uclibc.
Rather than passing in -largp via the recipe, patch the configure script to
provide an argument for the libargp usage and check for it when needed, and
use PACKAGECONFIG. The initial patch to check for libargp and use it if
available came from Gentoo. The patches are kept separate despite the second
modifying what the first does, in order to keep the history/origin clear.

Adding this recipe to oe-core will allow it to be used by qemu to
provide a way to generate additional entropy needed to fix hangs
with getrandom().
Additional kernel config options have already been added to the
default qemu kernel configs.
