There used to be a mechanism using which packages could leave a
.fakeroot.<something> file which could contain commands to be executed
within the fakeroot environment. Since this mechanism is no longer
used by any package, remove it from the common infrastructure.
The latest user was nfs-utils, which used this mechanism to do the
"make install" as root, since doing otherwise was not supported. But
since 16e7b8255c, nfs-utils has been
upgraded and converted to the package infrastructure, and this hack is
no longer necessary. Another past user was the ltp-testsuite package,
for the same reason, and since
a72a670489, the fakeroot hack is no
longer needed.

Although support/dependencies/dependencies.sh checks for the version of make,
this script doesn't get a chance to run if make encounters a syntax error as a
result of being too old.
For example, the following syntax is only supported from make 3.81 onwards:
ifeq ($(BR2_TOOLCHAIN_BUILDROOT),y)
include toolchain/toolchain-buildroot.mk
else ifeq ($(BR2_TOOLCHAIN_EXTERNAL),y)
include toolchain/toolchain-external.mk
else ifeq ($(BR2_TOOLCHAIN_CTNG),y)
include toolchain/toolchain-crosstool-ng.mk

the dl directory would normally be created by the first wget download. If there are no such downloads, e.g. because you use a local download mirror (e.g. scp, file) or only use git/svn/hg/bzr repositories, the dl directory is not created automatically.

Add a simple toolchain wrapper for external toolchains, which forces the
correct sysroot/march/mtune/floating point options needed to use it
with buildroot.
With this in place the external toolchain behaves similar to the internal
ones, and the special handling can be removed. This also means that the
toolchain is usable outside buildroot without having to pass any special
compiler flags.
Also adjust the downloadable external toolchain support to install under
HOST_DIR so it can be used after the temporary build files are removed.

$(MAKE) $(EXTRAMAKEARGS) HOSTCC="$(HOSTCC_NOCCACHE)" HOSTCXX="$(HOSTCXX_NOCCACHE)" silentoldconfig
then, the Makefile in package/config inherits from HOSTCC/HOSTCXX
values with the ccache prefix. However, if we start from a cleaned
build (after make clean), ccache is not compiled yet, so things break.
To solve this, we pass a noccache variant of HOSTCC/HOSTCXX down to

Once a profile has been choosen, the user is offered the choice of
either letting Buildroot download and install the external toolchain,
or (as before) to tell Buildroot where the toolchain is installed on
the system.
We of course provide a "custom profile", through which the user can

Ensure host packages (dependencies of target packages) are also handled
by make source / make external-deps.
This has to be done a explicitly, as we don't list these in Kconfig,
and hence also not in a variable like TARGETS, so instead we have to
look at the <PKG>_DEPENDENCIES variables for each enabled package and
extract the host packages from there.
Host packages can in turn also have dependencies, so we have to follow
those as well. Ideally this should be done recursively, but as that's
pretty hard to do in make, it is limited to 1 level for now.
Finally, host packages share source files with target packages, so
pipe output of make external-deps through sort -u to ensure duplicates
are removed.

The configuration cache shared between packages, while being in
principle a nice idea to speed-up the configuration of packages by
avoiding repetitive identical checks, turned out to be unreliable due
to the subtle differences between similar but not identical checks in
different packages. After spending some time trying to fix those, we
concluded that supporting the shared configuration cache is definitely
too hard and too unreliable, and that we'd better get rid of it
