Add option to compile all host tools even if not needed.
This can be useful to prepare a universal precompiled host tools
archive to use in another buildroot and speedup compilation.

When we use the internal toolchain USE_SSTRIP will be selected by
default for musl libc and USE_STRIP when glibc is used. Do the same when
an external toolchain is used. USE_GLIBC will also be set for external
toolchain builds based on the EXTERNAL_TOOLCHAIN_LIBC_USE_GLIBC setting.

Remove flags from wget and curl instructing them to ignore bad server
certificates. Although other mechanisms can protect against malicious
modifications of downloads, other vectors of attack may be available
to an adversary.
TLS certificate verification can be disabled by turning oof the
"Enable TLS certificate verification during package download" option
enabled by default in the "Global build settings" in "make menuconfig"

Disabling this build tunable breaks build and seems unrealistically
likely to be fixed.
This patch sets the related CONFIG to always true and removes the
config prompt, keeping the change minimal, and, should !CONFIG_IPV6 ever
be fixed, easy to revert.

Generate BTF (BPF Type Format) information from DWARF debug info. This is
embedded in the kernel and exported via sysfs as /sys/kernel/btf/vmlinux.
BTF data enhances kernel portability and introspection for BPF programs.
Selecting this also enables the dwarves host package which provides the
pahole tool used for BTF encoding.
Test using: "bpftool btf dump file /sys/kernel/btf/vmlinux format c"
This needs to depend on KERNEL_DEBUG_INFO_REDUCED not being set,
otherwise we can enable both KERNEL_DEBUG_INFO_BTF and
KERNEL_DEBUG_INFO_REDUCED, which will result in undefined behaviour.

Add DEBUG_INFO_REDUCED as a kernel config option and remove it from the
kernel configs. This is in preparation of the upcoming option to enable
BTF typeinfo, which is incompatible with DEBUG_INFO_REDUCED.

Add option to compile kmod-vrf, support for Virtual Routing and
Forwarding (Lite).
This module depends on NET_L3_MASTER_DEV, which is a boolean kernel
option, so we need to create a configuration option also for this, and
make kmod-vrf depend on it.

Certain utilities, such as smcroute [1], require additional multicast
routing options to be enabled, otherwise they will not function
correctly. Enable these relevant dependancies when IPv4 and/or IPv6
multicast routing are enabled.

Enabling KERNEL_UBSAN exposes several missing symbols. Add new kernel
build options for UBSAN_BOUNDS and UBSAN_TRAP, disable CONFIG_TEST_UBSAN
in the generic kernel configs and enable CONFIG_UBSAN_MISC in generic
5.10 config. The latter symbol was removed in later kernels, as it was
causing some issues, so just disable it in 5.10 instead of adding a
build option for it.

Enabling KERNEL_KASAN exposes several missing symbols. As KASAN_SW_TAGS
is only implemented for arm64 CPUs and requires clang, it doesn't make
