The problem with the current implementation in the GLOBAL_INSTRUMENTATION_HOOKS is that we only capture what is installed in $(HOST_DIR) during the "host installation step", what is installed in $(TARGET_DIR) during the "target installation step" and what is installed in "$(STAGING_DIR)" during the staging installation step. While this seems reasonable in principle, it is in fact not completely true. For example, "toolchain", which is a target package, installs tons of files in $(HOST_DIR). "qt5base", which is also a target package, also installs things in $(HOST_DIR). Same with the "syslinux" package. The idea behind this patch is pretty simple: - At the beginning of the configure step, right after the per-package directories have been populated (if BR2_PER_PACKAGE_DIRECTORIES=y), we capture the state of the HOST_DIR, TARGET_DIR and STAGING_DIR. - At the end of all install steps (which is possible thanks to the newly introduced "install" step), we capture again the state of HOST_DIR, TARGET_DIR and STAGING_DIR, and compare it to what we have saved at the configure step. So regardless of whether a file has been installed in $(HOST_DIR) during the target or staging installation steps of a target package, or if a host package has installed a file in $(TARGET_DIR), we will detect it. The pkg_size_before and pkg_size_after macros are intentionally left where they are (even if they now fall in the middle of the GLOBAL_INSTRUMENTATION_HOOKS implementations) to minimize the diffstat and facilitate review. Note that we also have to change check_bin_arch to be explicitly called from the install step rather than through a GLOBAL_INSTRUMENTATION_HOOKS as it depends on the .files-list.txt file produced by the pkg_size_after function.
