Almost all packages which are saved for legal-info have their source
archives downloaded as part of 'make source', which makes an off-line
build completely possible [0].
However, for the pre-configured external toolchains, the source tarball
is different, as the main tarball is a binary package. And that source
tarball is only downloaded during the legal-info phase, which makes it
inconvenient for full off-line builds.
We fix that by adding a new rule, $(1)-legal-source which only
$(1)-all-source depends on, so that we only download it for a top-level
'make source', not as part of the standard download mechanism (i.e. only
what is really needed to build).
This new rule depends, like the normal download mechanism, on a stamp
file, so that we do not emit a spurious hash-check message on successive
runs of 'make source'.
This way, we can do a complete [0] off-line build and are still able to
generate legal-info, while at the same time we do not incur any download
overhead during a simple build.
Also, we previously downloaded the _ACTUAL_SOURCE_TARBALL when it was
not empty. However, since _ACTUAL_SOURCE_TARBALL defaults to the value
of _SOURCE, it can not be empty when _SOURCE is not. Thus, we'd get a
spurious report of a missing hash for the tarball, since it was not in
a standard package rule (configure, build, install..) and thus would
miss the PKG and PKGDIR variables to find the .hash file.
We fix that in this commit as well, by:
- setting PKG and PKGDIR just for the -legal-source rule;
- only downloading _ACTUAL_SOURCE_TARBALL if it is not empty *and* not
the same as _SOURCE (to avoid a second report about the hash).
[0] Save for nodejs which invarriably wants to download stuff at build
time. Sigh... :-( Fixing that is work for another time...

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
