Fix CVE-2023-3341: The code that processes control channel messages sent
to `named` calls certain functions recursively during packet parsing.
Recursion depth is only limited by the maximum accepted packet size;
depending on the environment, this may cause the packet-parsing code to
run out of available stack memory, causing `named` to terminate
unexpectedly. Since each incoming control channel message is fully
parsed before its contents are authenticated, exploiting this flaw does
not require the attacker to hold a valid RNDC key; only network access
to the control channel's configured TCP port is necessary. This issue
affects BIND 9 versions 9.2.0 through 9.16.43, 9.18.0 through 9.18.18,
9.19.0 through 9.19.16, 9.9.3-S1 through 9.16.43-S1, and 9.18.0-S1
through 9.18.18-S1.

The bind package exhibits gcc bug 101737 when built for the SH4
architecture with optimization enabled, which causes a build failure.
As done for other packages in Buildroot work around this gcc bug by
setting optimization to -O0 if BR2_TOOLCHAIN_HAS_GCC_BUG_101737=y.
To achieve this we need to correct the override of CFLAGS by using:
BIND_CONF_OPTS += CFLAGS="$(BIND_CFLAGS)"
instead of:
BIND_CONF_ENV = BUILD_CFLAGS"$(BIND_CFLAGS)"
since the latter doesn't work as expected and doesn't override CFLAGS.

It's been ages (5 years at the next release) that we've not installed
host packages in $(HOST_DIR)/usr, but we still have a few packages that
reference it or install things in there.
Drop all of those in one fell swoop.

should exercise all touched packages [*], does build:

ages, and other packages already reference the correct location for
llvm-config, so it was assumed that is OK.

Fixes the following security issues:
- A malformed incoming IXFR transfer could trigger an assertion failure in
named, causing it to quit abnormally. (CVE-2021-25214)
- named crashed when a DNAME record placed in the ANSWER section during
DNAME chasing turned out to be the final answer to a client query.
(CVE-2021-25215)
- When a server's configuration set the tkey-gssapi-keytab or
tkey-gssapi-credential option, a specially crafted GSS-TSIG query could
cause a buffer overflow in the ISC implementation of SPNEGO (a protocol
enabling negotiation of the security mechanism used for GSSAPI
authentication). This flaw could be exploited to crash named binaries
compiled for 64-bit platforms, and could enable remote code execution when
named was compiled for 32-bit platforms. (CVE-2021-25216)

There had existed in one of the ISC BIND libraries a bug in a
function that was used by dhcpd when operating in DHCPv6 mode.
There was also a bug in dhcpd relating to the use of this function
per its documentation, but the bug in the library function
prevented this from causing any harm. All releases of dhcpd from
ISC contain copies of this, and other, BIND libraries in
combinations that have been tested prior to release and are known
to not present issues like this.
Affects: Builds of dhcpd versions prior to version 4.4.1 when
using BIND versions 9.11.2 or later.

Fixes the following security issue:
- CVE-2020-8625: When tkey-gssapi-keytab or tkey-gssapi-credential was
configured, a specially crafted GSS-TSIG query could cause a buffer
overflow in the ISC implementation of SPNEGO (a protocol enabling
negotiation of the security mechanism to use for GSSAPI authentication).
This flaw could be exploited to crash named. Theoretically, it also
enabled remote code execution, but achieving the latter is very difficult
in real-world conditions
