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... Signed-off-by: "Yann E.
