Paul Spooren 3572711e3c build: refactor JSON info files to `profiles.json` JSON info files contain machine readable information of built profiles and resulting images. These files were added in commit `881ed09ee6` ("build: create JSON files containing image info"). They are useful for firmware wizards and script checking for reproducibility. Currently all JSON files are stored next to the built images, resulting in up to 168 individual files for the ath79/generic target. This patch refactors the JSON creation to store individual per image (not per profile) files in $(BUILD_DIR)/json_info_files and create an single overview file called `profiles.json` in the target directory. Storing per image files and not per profile solves the problem of parallel file writes. If a profiles sysupgrade and factory image are finished at the same time both processes would write to the same JSON file, resulting in randomly broken outputs. Some target like x86/64 do not use the image code yet, resulting in missing JSON files. If no JSON info files were created, no `profiles.json` files is created as it would be empty anyway. As before, this creation is enabled by default only if `BUILDBOT` is set. Tested via buildroot & ImageBuilder on ath79/generic, imx6 and x86/64.

 -----------------------------------------------------

This is the buildsystem for the OpenWrt Linux distribution.

To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.

You need gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.

1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default

2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/

3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.

4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
