Hi all,
this patch set aims to improve build reproducibility by using a
per-package staging directory.
Also this feature aims to enable as default the top-level parallel make.

Every package instead of installing the files in the shared staging
directory (STAGING_DIR) install all files in a subdirectory of the

At the begginning of the configure stage, all the dependencies staging
directory are copied in the package staging directory, e.g.:

zlib-install-staging: insall files in /output/stagingpkg/zlib/

cramsfs-configure: copy all files from /output/stagingpkg/zlib/* to

The STAGING_DIR variable is redefined for every package in order to
point to the per-package directory, so a package cannot access
automatically to staging files of packages that aren't in the

The most significant changes are in the pkg-generic.mk files.

The other modifications are just to be able to access to per-package
staging directory, like adding -L$(STAGING)/usr/lib or -I$(STAGING)/usr/include

This patch set is a working in progess, but it seems to builds fine
the configuration that i mangaged to test.

 - clean up
 - rebase over master, right now is based on the 2015.02 release (I've
   not rebased it because there are some regressions on master after
   the merge of the next branch)
 - test more packages (I've not done it, because there are already
   build problems without using this patch set, at least on Fedora 21)

For convenience this patch set is avaiable in the branch "pps-2015.02"
of the repository https://github.com/fabio-porcedda/buildroot.git

This patch set is based on the release 2015.02, it builds fine the
following configuration on a Fedora 21:
  make distclean defconfig allyespackageconfig -s && sed -e "s/BR2_PACKAGE_LUAJIT=y//" -i .config && yes '' | make oldconfig
  make BR2_JLEVEL= -j$((`getconf _NPROCESSORS_ONLN`+1))
