This reduces open coding and allows to easily add a knob to enable
it treewide, where chosen packages can still opt-out via "no-lto".
Some packages used LTO, but not the linker plugin. This unifies 'em
all to attempt to produce better code.
Quoting man gcc(1):
"This improves the quality of optimization by exposing more code to the
link-time optimizer."
Also use -flto=auto instead of -flto=jobserver, as it's not guaranteed
that every buildsystem uses +$(MAKE) correctly.

The nslookup_lede/openwrt applet was introduced in de5b8e5. It was
introduced because:
Add a new LEDE nslookup applet which is compatible with musl libc
and providing more features like ability to specify query type.
In contrast to busybox' builtin nslookup applet, this variant does
not rely on libc resolver internals but uses explicit send logic
and the libresolv primitives to parse received DNS responses.
In busybox this applet is added in 0dd3be8. In particular, this commit
introduces the variable NSLOOKUP_BIG. We set the default to true and
so nothing changes.

PREFER_IPV4_ADDRESS is broken on IPv6-only hosts, as it causes busybox
utilities (ping, traceroute, ntpd) to forcibly use the A record instead of
the AAAA record when resolving a DNS name. This obviously fails when
there is no IPv4 connectivity. Since IPv6-only hosts or routers will only
become more common over time, disable PREFER_IPV4_ADDRESS to support this
use-case.
As a side-effect, disabling PREFER_IPV4_ADDRESS changes the default
resolution behaviour of busybox utilities on dual-stack hosts. Busybox
utilities now simply use the order given by getaddrinfo(), so they will
now prefer IPv6 addresses when resolving a name with both A and AAAA
records if there is IPv6 connectivity. This is in line with RFC 6724.
PREFER_IPV4_ADDRESS was likely intended to work around naive
implementations of getaddrinfo() that could return AAAA records first,
even on an IPv4-only host. But both musl (since 1.1.3) and glibc
correctly implement RFC 6724 for getaddrinfo() and check connectivity to
determine the correct order in which to return records. On IPv4-only
hosts, getaddrinfo() will return A records first, so there is no need for
the PREFER_IPV4_ADDRESS hack.

Before this commit, it was assumed that mkhash is in the PATH. While
this was fine for the normal build workflow, this led to some issues if
make TOPDIR="$(pwd)" -C "$pkgdir" compile
was called manually. In most of the cases, I just saw warnings like this:
make: Entering directory '/home/.../package/gluon-status-page'
bash: line 1: mkhash: command not found

OpenWrt target images (the kernel image is unchanged, obviously):

Commit ad7c6102f2 ("busybox: fix missing install with suid bit set if

thus would install busybox setuid root by default which would result in
possibly unwanted change of current behaviour, so let's disable this
option by default in order to preserve the current status-quo.
For the record: disabling FEATURE_SUID to preserve the status-quo does
*not* imply the current status-quo is "safer", or for that matter, in
any way desireable. That is a discussion to be had on the mailing

Switching the FEATURE_SUID default to "n" is simply a compromise to
