Currently, the output of printvars copntains the name of the variable,
its expanded value and its un-expanded value.
However, most of the time, we need the actual, expanded value, so it can
be re-used from a (non-Buildroot) infrastructure script, like a
post-build script, or a build-farm driver (e.g. a Jenkins job...)
Add two options that a user may set to change the output of printvars:
- QUOTED_VARS, if set, will quote the value
- RAW_VARS, if set, will print the unexpanded value
The new output by default only prints the expanded value now.
So that it can be used as such:
$ make -s printvars VARS=BUSYBOX_VERSION
BUSYBOX_VERSION=1.26.2
$ make -s printvars VARS=BUSYBOX_RDEPENDENCIES QUOTED_VARS=YES
BUSYBOX_RDEPENDENCIES='ncurses util-linux'
$ make -s printvars VARS=BUSYBOX_FINAL_PATCH_DEPENDENCIES RAW_VARS=YES
BUSYBOX_FINAL_PATCH_DEPENDENCIES=$(sort $(BUSYBOX_PATCH_DEPENDENCIES))
And it is even possible to directly evaluate it in a shell script:
eval $(make -s printvars VARS=BUSYBOX_VERSION QUOTED_VARS=YES)
Backward compatibility of the output is not maintained. It is believed
that scripts that depended on the previous output were very fragile to
begin with, because they had to filter the non-formatted output
(splitting on spaces or braces was not really possible, because values
could contain either).
Document printvars and its options in the manual; list it in the output
of 'make help'.

Since we now require Lua package names to start with "lua", it is likely
that the Buildroot name is different from the upstream LuaRocks name.
Add a feature to the luarocks-package infra that makes it easier to
handle this situation: the package can explicitly specify the upstream
name in PKG_NAME_UPSTREAM, and that name will be used in PKG_ROCKSPEC,
PKG_SOURCE and PKG_SUBDIR.
Add an explanation of this feature to the manual. To make the example
relevant, it is changed to lua-foo, where the upstream name is plain
foo. To avoid confusion with the dependency on a native library, that
dependency is renamed to bar.

We currently have two places where we recommend where BR2_DL_DIR
should be set: "Environment variables" and "Location of downloaded
packages". The former recommends setting BR2_DL_DIR in the .config,
the latter kind of endorses using ~/.bashrc.
We prefer suggesting the ~/.bashrc way since it avoids downloading the
same file multiple times, and anyway it's wise to have all the details
in a unique place. So remove the .config suggestion from "Environment
variables" and let it just point to "Location of downloaded packages".

Recently, the autoconf macros for libtool started using '/usr/bin/file'
to determine the type of library that is generated by the toolchain.
Packages that use this recent version of the libtool autoconf macros
will fail in a rather dramatic way when /usr/bin/file is not present
on the host: the package will still build but no shared library is
generated, which in turn may cause build failures in other packages
that link with it.
For example, libpng's configure determines that it is not possible to
build a shared library on MIPS64 because the expected output from 'file'
is not present. Therefore, only a static libpng.a is built. Later,
bandwithd links with -lpng but it doesn't use the pkg-config's
Private-Libs (because it's not linking statically) and it doesn't have
access to the NEEDED reference from the shared library. Therefore, it
doesn't link with zlib and fails with
pngrutil.c:(.text+0x55c): undefined reference to `inflate'
We cant use host-file because it is itself an autotools package and is
itself using libtool, so this would be a chicken-n-egg problem. Besides,
the libtool script really wants to call /usr/bin/file, so it would not
even find our host-file anyway.
So, just require that '/usr/bin/file' is present on the host.

While BR2_EXTERNAL_<NAME>_PATH was already documented, it was not
made obvious that it could be reused in post-biuld, post-image and
in-fakeroot scripts.
The BR2_EXTERNAL_<NAME>_DESC variable was not documented at all.
Update the manual to fix this.
Note: a2x chokes on this:
.Note:
Both +BR2_EXTERNAL_$(NAME)_PATH+ and +BR2_EXTERNAL_$(NAME)_DESC+ are
available [...]
and spits out a totally useless error message:
a2x: ERROR: "xsltproc" --stringparam toc.section.depth 1 --stringparam
callout.graphics 0 --stringparam navig.graphics 0 --stringparam
admon.textlabel 1 --stringparam admon.graphic 0 --stringparam

So, we had to resort to using different quoting styles for each
variables. They are not semantically equivalent, but the rendering
is the same with the default CSS (which we are using). That's gonna
be good-enough for now...

Currently, it is not possible for a br2-external tree to override a
defconfig bundled in Buildroot, nor is it possible to override one from
a previous br2-external tree in the stack.
However, it is interesting that a latter br2-external tree be able to
override a defconfig:
- the ones bundled in Buildroot are minimalist, and almost always
build a toolchain, so a br2-external tree may want to provide a
"better" defconfig (better, in the sense "suited for the project");
- similarly for a defconfig from a previous br2-external tree.
But we can't do that, as the rules for the defconfigs are generated in
the order the br2-external trees are specified, all after the bundled
defconfigs. Those rule are patten-matching rules, which means that the
first one to match is used, and the following ones are ignored.
Add a new utility macro, 'reverse', inspired from GMSL, that does what
it says: reverse a list of words.
Use that macro to reverse the list of br2-external trees, so that the
latters win over the formers, and even over bundled ones.
