toolchain/helpers.mk: fix creation of DESTDIR in copy_toolchain_lib_root

In commit b3cc7e65ee, the definition of the DESTDIR variable was moved
down into the loop that follows symlinks in the libraries that are
copied to target. However, the corresponding mkdir was not moved down,
so that no directories are ever created.

In practice, this mkdir is normally redundant since the directories
should already have been created as part of creating STAGING_DIR.
Still, the current situation is clearly wrong, so fix it by moving the
mkdir down to after the assignment to DESTDIR.

While we're at it, also remove a redundant empty line. It's a leftover
from when a lot of variables were declared above.

This simply updates to the latest stable release. WebKitGTK+ versions
in the 2.1x series avoid bumping the dependencies in order to allow
distributions to provide updates, therefore no new dependencies are

execline: remove --shebangdir configure option

The host build passes the --shebangdir configure option, the target
build doesn't.  With the removal of $(HOST_DIR)/usr, it is not clear
if this should be /bin or /usr/bin or $(HOST_DIR)/bin. Looking at the
source code, it turns out that this variable is not used at all, and
/usr/bin doesn't appear anywhere in the installed files.

Since it is not clear what this option should be set to, and it
anyway doesn't do anything, remove it entirely.

policycoreutils: rework host installation

policycoreutils has a pretty peculiar interpretation of DESTDIR and
PREFIX.  PREFIX is not consistently used: some installation paths and
include paths are forced to $(DESTDIR)/usr/... . In other cases,
PREFIX is indeed used. PREFIX defaults to $(DESTDIR)/usr

Try to be a little bit more correct by passing both DESTDIR and PREFIX,
both set to $(HOST_DIR). This is not a complete fix: some things are
still installed in $(HOST_DIR)/usr - but nothing we care about (just
manpages, systemd services, ...). More importantly, however, it still
looks for e.g. D-Bus in $(DESTDIR)/usr/include/dbus-1.0.

Still, it's better than nothing.

busybox: disable CONFIG_FEATURE_CLEAN_UP in default configs

FEATURE_CLEAN_UP is a configuration feature to get busybox to explicitly
call free() on dynamic allocated memory just before exiting so memory leak
detectors like valgrind don't get confused.  Upstream explicitly recommends
to NOT enable this option:

config FEATURE_CLEAN_UP
bool "Clean up all memory before exiting (usually not needed)"
default n
help
  As a size optimization, busybox normally exits without explicitly
  freeing dynamically allocated memory or closing files. This saves
  space since the OS will clean up for us, but it can confuse debuggers
  like valgrind, which report tons of memory and resource leaks.

  Don't enable this unless you have a really good reason to clean
  things up manually.

Having this option enabled adds a bit of bloat, but more significantly these
cleanup code paths don't get tested very often so some times get out of sync
with the allocation code which can lead to crashes (or security issues from
double frees), so it is safer to disable the option.

For people wanting to debug memory leak issues with busybox, the option can
still be enabled with a configuration fragment (or a custom config).

The size difference isn't huge (br-arm-full-static):

toolchain/helpers.mk: simplify ld.so fixup in copy_toolchain_sysroot

In copy_toolchain_sysroot, if no ld.so has been found in the
STAGING_DIR after the sysroot copy, we look at ARCH_SYSROOT_DIR if a
ld.so is available there. We do this for both ld*.so and ld*.so.*.

However, when copying thing from staging to target (as listed in
TOOLCHAIN_EXTERNAL_LIBS), we only match on ld*.so.*. This would mean
that even if a dynamic linker matching ld*.so but not ld*.so.* was
copied into staging by copy_toolchain_sysroot, it would anyway not be
copied to the target filesystem, making the system unusable.

toolchain-external: copy ld*.so* for all C libraries

Currently, for the dynamic loader, we're copying ld*.so* for glibc and
uClibc, except for glibc/EABIhf where we are explicitly copying
ld-linux-armhf.so.*. For musl, we're not copying the dynamic linker
because it's simply a symbolic link to libc.so. However, the name of
the musl dynamic linker changes from one architecture to the other,
and we don't handle all cases.

Since handling the musl dynamic linker symlink creation is becoming
more and more annoying to maintain, this commit makes musl use the
same mechanism as glibc/uClibc: put the dynamic linker in
TOOLCHAIN_EXTERNAL_LIBS.

In addition, the special condition on glibc/EABIhf was added in
11ec38b6950cf3337b52fb97f27c2fd7c776c5c2 ("toolchain-external: fix
Linaro ARM toolchain support") because an old Linaro toolchain had two
dynamic loaders, and we wanted to copy only one. But 1/ this is old
and 2/ having the two dynamic linkers doesn't really matter.

So this commit simply unconditionally adds "ld*.so*" to
TOOLCHAIN_EXTERNAL_LIBS, regardless of the C library being chosen. It
re-uses the musl dynamic linker symlink from the sysroot, which makes
it always correct, and allows us to remove the
TOOLCHAIN_EXTERNAL_MUSL_LD_LINK hook, and all the related logic.

This commit therefore solves two problems with the musl dynamic linker
symbolic link creation logic:

 1 We support all architectures, without having to hardcode in
   Buildroot the mapping between the CPU architecture and the
   corresponding dynamic linker name. For example, our current logic
   was not handling the mips64+n32 ABI case, where the dynamic linker
   is named ld-musl-mipsn32el.so.1.

 2 We support Crosstool-NG musl toolchains, where the dynamic linker
   is in /lib, but libc.so is in /usr/lib.

toolchain/helpers.mk: re-evaluate DESTDIR in copy_toolchain_lib_root

copy_toolchain_lib_root copies libraries from staging to target,
resolving and copying symbolic links along the way.

The most inner loop, a "while" loop, starts from an initial name, and
if it's a symbolic link, gets resolved to the target, and the loop
iterates until we reach a real file. However, the destination folder
where the symbolic link or real file is created is computed in DESTDIR
only once, before this loop starts. Therefore, this loop works fine
when all symbolic links in the chain, and the real file all belong to
the same directory. But it doesn't do the correct thing when the
symbolic link and/or real file are in different folder.

An example is Crosstool-NG musl toolchains, where the dynamic loader
is in /lib/ld-musl*.so but points to ../usr/lib/libc.so. With the
current logic, we copy /lib/ld-musl*.so to /lib, but we also copy
libc.so to /lib instead of the expected /usr/lib.

This currently doesn't cause any problem because the musl dynamic
linker is manually created by the TOOLCHAIN_EXTERNAL_MUSL_LD_LINK
hook. However, this logic has a number of problems, so in a followup
commit, we are going to put the musl dynamic linker in
TOOLCHAIN_EXTERNAL_LIBS, which will cause it to be copied by
copy_toolchain_lib_root. But we obviously want the link and its target
to be copied to the right place, hence this fix.

Eliminate $(HOST_DIR)/usr

We currently use $(HOST_DIR)/usr as the prefix for host packages. That
has a few disadvantages:

- There are some things installed in $(HOST_DIR)/etc and
  $(HOST_DIR)/sbin, which is inconsistent.

- To pack a buildroot-built toolchain into a tarball for use as an
  external toolchain, you have to pack output/host/usr instead of the
  more obvious output/host.

- Because of the above, the internal toolchain wrapper breaks which
  forces us to work around it (call the actual toolchain executable
  directly). This is OK for us, but when used in another build system,
  that's a problem.

- Paths are four characters longer.

To allow us to gradually eliminate $(HOST_DIR)/usr while building
packages, replace it with a symlink to .

The symlinks from $(HOST_DIR)/usr/$(GNU_TARGET_NAME) and
$(HOST_DIR)/usr/lib that were added previously are removed again.

Note that the symlink creation will break when $(HOST_DIR)/usr
already exists as a directory, i.e. when rebuilding in an existing
output directory. This is necessary: if we don't break it now, the
following commits (which remove the usr part from various variables)
_will_ break it.

At the same time as creating this symlink, we have to update the
external toolchain wrapper and the external toolchain symlinks to go
one directory less up. Indeed, $(HOST_DIR) is one level less up than
it was before.

Move $(HOST_DIR)/usr/lib to $(HOST_DIR)/lib

This is a step towards eliminating $(HOST_DIR)/usr. It allows us to
convert all packages installing things into $(HOST_DIR)/usr/lib without
affecting the rest.

To allow compatibility with packages that still use $(HOST_DIR)/usr as

Note that the symlink creation will break when $(HOST_DIR)/usr/lib

check-host-rpath script to accept both $(HOST_DIR)/usr/lib and
$(HOST_DIR)/lib, because depending on how the package derives the
path, it may be different.

Since there are some dependency chains that involve $(STAGING_DIR),
$(STAGING_DIR) may in fact be created before $(HOST_DIR). Since
$(STAGING_DIR) is a subdirectory of $(HOST_DIR), it is possible that the
newly added rule for $(HOST_DIR) never triggers. To make sure that the
rule does trigger, add an order-only dependency from $(STAGING_DIR) to

whois: use the new gettext logic

This commit switches to use the new gettext logic, which involves:

 - using TARGET_NLS_DEPENDENCIES instead of hand-encoded dependencies
   on gettext/host-gettext

 - using TARGET_NLS_LIBS to force linking against libintl

 - dropping BR2_PACKAGE_GETTEXT selection, which means we no longer
   need to depend on BR2_USE_WCHAR, so this dependency is dropped
